Prusa Connect Keeps Showing Printer is Offline

Prusa Connect just suddenly started displaying that my MK-4S is offline.  It will sometimes show it is connected until I try to upload a file then it disconnects.  Tried rebooting the printer & re-login into Connect but no luck   Is this common & does anyone know of a fix?

Been having this issue all day. Curious what the issue could be since the status page has everything as green.

Thanks. Good to know. Is there a workaround known?

I'd delete the printer from Connect and start again, but I don't see a way to delete a printer or all printers. How can I do that?

RE: Prusa Connect Keeps Showing Printer is Offline

Having a similar issue with the XL and Prusa Connect. Noticed it tonight about 4 hours into a new print started this evening. I don't want to stop the print to try to fix, as it was working fine for the last 2 day print that just completed. Printer is printing, but reports as being OFFLINE. The esp32 camera is updating images though. Interesting, if I log into the camera and manually send an image, the status goes to PRINTING, but shows <1min left in the print job. This also seems to happen every few minutes on its own, without manually pushing an image from esp32 cam. See image below.

I just started print runs that last 2-3 days each. It would be really helpful to have Connect reporting the correct data so I can check in on it while out...

Same.

Works on my phone (connected to same WiFi).

Computer says the printer is Offline in both PrusaSlicer and when I connect to connect.prusa3d.com.

RE:

Same issue on my mk4s I was running the recent alpha release to solve the mmu overcurrent fault on startup then this issue started. I saw that the official release was out so I downloaded it to the printer manually thinking the alpha was the problem with no luck. Seems like I'm just going from one software issue to the next with Prusa. I'll try to delete and re add the printer after this print is done in 30 mins or so and post back here if I have any luck.

Is there a status page to check for known service issues like this? If I've missed something I apologise.

I don't know but I've seen reports on reddit & github dating back to January so it seems like the problem has been around for a while now for some users.

Everything was working fine for me yesterday but today ( without any assistance by me ), my printers all started showing OFFLINE in Connect.

Well, it looks like there is a status page at https://status.prusa3d.com/

However, it shows Connect as down for 2 minutes so far.

No luck. Went the full 9 yards just to see. Deleted prusa slicer downloaded newest version, replaced the usb with a new one and formatted it in FAT32 loaded it up with the newest firmware for mk4s, and took the ridiculous step of factory resetting, and dumping the new firmware on it. Took awhile to get through setup did not think that through. Printers up and running with completely fresh and up to date software on every end I control. Same problem absolutely no change. It connects to wifi just fine, but not prusa connect. I don't know enough about the deeper end of network issue troubleshooting to keep going so I guess I'm just moving the USB back and forth now. I'm opening a ticket as well.

RE:

Not sure why the status page shows everything as up, it definitely is down and has been all day.

Mine is still down too and has been down pretty much half the day. I tried removing and adding the printer again. But no change. Intermittently Prusa Connect will show my printer as printing or idle. I have been using the USB drive to print and I get the notifications when print is finished. I guess that occurs due to the intermittent connection.

I'm having the same issues with all of my printers, it would be really nice if this was reported correctly so I didn't try to debug it for hours.

Same for me. But this behaviour is the same ever since I bought the printer ( January 2024 ).
