PrusaConnect keeps showing OFFLINE and other connection issues
I'm just about to go back to using a memory stick, because this is frankly hopeless. It used to work tolerably well using the wired LAN connection, but because it wasn't always powered up, I'd find that it wouldn't connect because the IP address keeps changing. Why can't we have a static IP address for this, it would be so much more reliable, rather than having to keep going into the settings and changing the IP address?
This had got so painful that I decided to use WiFi instead. That seemed to work ok for a while, but now I'm getting OFFLINE status showing all the time, and I'm having to keep turning off the printer and waiting, then trying again to see it it will finally connect. Most times it doesn't.
That's even worse than changing the IP address, so I went back to wired LAN again, and now it's showing OFFLINE all the time too! Grrrrrrrr....
Going into the settings for the printer on PrusaSlicer, it tests ok, but still shows OFFLINE. So it appears that the connection is fine, but the printer just won't communicate the status correctly.
Can someone have a look at these issues, because it's driving me nuts?
Thanks.

That's something you have to set on your router. It should have an option to tie a static IP address to a device MAC address.

RE: PrusaConnect keeps showing OFFLINE and other connection issues
I'm getting this too. Seems to have started happening after the latest release. This morning is typical - Connect was connected, I set up and started a print and everything was good. But when checking back its says OFFLINE so I have to physically go to the printer to check progress. It's annoying and I'd expect better from Prusa. My other printer that runs Klipper and is in the same room as my Prusa Mk4S is fine - I can't recall it ever being offline. My mesh WiFi signal is strong and robust. Someone needs to look at the Connect connection protocols as something is off.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
In desperation, I deleted the printer from PrusaConnect and reconnected it. So far, that seems to have fixed the issue. If that's the case, then there's something in the installed parameters that's causing this issues, because nothing else has changed.
I'll look into the Static IP address once these print jobs are complete
RE: PrusaConnect keeps showing OFFLINE and other connection issues
How do you delete a printer?
RE: PrusaConnect keeps showing OFFLINE and other connection issues
Well add me to the list. Showing offline when it's clearly not offline. I'm getting frustrated and have tried everything. Doesn't help that customer service has over a half hour waiting time to talk
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I am having this same issue with my MK4 and XL 5T. It just keeps going on and offline and the printer screen network menu shows me an Error status with a Prusa Connect SRV Error prompt??
RE: PrusaConnect keeps showing OFFLINE and other connection issues
You can remove a printer by going into Prusaconnect, click on the Printer you want to remove and then go to the Settings tab. Scroll down to the bottom and you'll find a Remove Printer button. They suggest you use the Download Settings button on the same page first, but I didn't bother.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
Yea I’ve already done that 4 times already and even factory reset both printers. None of it has worked for me.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
About 10 minutes after the start of almost every print, Prusa Connect shows my Core One as offline even though the machine is printing normally. The offline/online status usually cycles several times during the print, but this morning Connect has shown the printer as offline for several hours.
Prusa Link works fine throughout, so I think the problem is with the Connect servers or Prusa's network infrastructure.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I have the same problem with the Core One. Connect goes offline after a few minutes and stays offline until shortly before the end of printing. It's very frustrating because the Buddy Camera doesn't work either then and since the Buddy Camera doesn't even have a LAN mode, the camera is useless and you can't monitor the print. I hope this problem will be fixed soon.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I've just finished building my first Prusa printer (Mk4S) and the lack of stability in Prusa Connect is very frustrating and annoying as part of the reason I chose this product was the networking. What's even more frustrating is that Prusa Connect seems excellent when it works, but I'm seeing multiple random periods of "OFFLINE". Monitoring the Prusa Connect settings on the LCD shows a sequence of messages, typically something like 'Refused', 'Refused' and then "Error" or "Network".
What's even more disturbing is that this seems to have been going on for about 3 months and Prusa has neither responded here nor done anything noticeable about it. I've just given my purchase 3 stars on Amazon instead of the 5 it really deserves simply because of this.
I have quite a lot of networking experience and I'd be happy to work with their customer support to help resolve the issue.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I don't have the nerve to do this. I have the printer connected to the Prusa Connect via LAN, I have a reserved fixed address for the printer in the router and I see "Status - Connected" there. But Connect reports OFFLINE almost the entire time I've been printing for several hours.No, I'd rather get an Octoprint for this printer too.

RE: PrusaConnect keeps showing OFFLINE and other connection issues
Same situation for me. I've set up my router to have fixed IP address matching that originally set up when I connected my Core One to Prusa Connect. In the last ~2 weeks my printer status has remained OFFLINE. I am unable to connect via Prusa Connect in Printables or using the Prusa App. Looking under Network Settings for my Prusa Connect status on my Core One, it shows an Error -- "Refused" as the connection status. From above comments, a best next guess attempt at removing my Core One and re-adding it to Prusa Connect sounds like not worth the time, as others have tried this and found it does not resolve the issue.
Prusa Connect usage is pretty awesome. Would appreciate an official troubleshooting guide for this issue.
I may try to use Prusa Link option instead (LAN based), but perhaps that doesn't integrate into PrusaSlicer EasyPrint.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
Still an issue today (4th August) after the latest update meant to optimise Prusa Connect… multiple core ones, MK4S and minis all showing “srv error” for 8 hours now. Pretty poor form to still have this issue.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I've arrived at this topic due to having this issue with my Core One.
After a certain amount of time, it's started showing offline in Prusa Connect (web and phone app show the same). The last percent complete on the print job in Prusa connect shows 26%, but the job on the printer is at 64% and still going.
The printer wifi status shows connected and I can see it connected from my wifi router.
From the app, I can view the Buddy camera feed live (I know that's a separate wifi device).
Tried disconnecting/reconnecting the Core one's wifi, but nothing.
I suspect when I reboot it, the same will repeat. It's connected for the first however long, then Prusa Connect shows it offline, (despite the printer always being connected to wifi)
Cheers,
Gary.
RE:
I'm having this issue with my Prusa XL as well. I started using Ethernet exclusively, and now Prusa Connect displays the Refused error message after an unknown amount of time after a print. The common error I see whenever this happens is "DNS Fail" in the network information settings. It starts working again after I switch the active network connection from Eth to Wifi back to Eth, which I think re-initializes the network interface and it grabs the correct DNS settings. After this Connect works immediately.
I think this has to do with the flaky network interface chipset/firmware. Even over ethernet speeds are super slow (because the network is running over a serial connection to the motherboard, I think). So this seems to be more issues with the network hardware/software itself, and not with Prusa Connect.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
I updated to firmware 6.2.6-alpha+8916 ( https://github.com/prusa3d/Prusa-Firmware-Buddy/releases) and this solved the problem, Prusa Connect remains connected and I haven't seen the Refused error in 24 hours. File transfers to the printer remain ridiculously slow and the estimated time remaining for the transfer is wildly inaccurate. I think the 4.5 MB file took around 3 minutes or so to upload, but the initial estimate in the Prusa Connect dashboard started at 15 mins and slowly came down over time. I can't imagine trying to upload an intricate slicing job, the upload would take hours, and the estimate would start at days. Just for the upload.
But I'm glad it works now. For really large files I would have to use USB instead of uploading through prusa connect. Which is a shame, because it is a really convenient feature otherwise.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
Had another failure. This time the error message was Network fail. Had to cycle the dhcp to static and back again, before Connect came online again. This is getting very frustrating.
RE: PrusaConnect keeps showing OFFLINE and other connection issues
This has been an intermittent issue with my MK4s. The only thing that seems to work is going in the settings menu and disabling Prusalink and PrusaConnect and re-enabling it. Sometimes it only takes one go at this, other times more. It works really well except for when it just randomly stops.
Most of the time, it is between prints. But, sometimes I've had it fail during a print so I can no longer monitor the progress.
