Adding my, me too.
My XL connects but my 3 MK4S printers will not connect.

Can't find a place in Prusa Link to schedule a print for a future time. So unless that feature is hidden Prusa Link is an inferior option.

On-Line Chat support confirmed server issue when I contacted them about 90 minutes ago for my XL 5TH. Said several of their support team were getting calls and they are trying to understand the server problem.

Same, issues with XL and showing Offline.
RE: Prusa Connect Keeps Showing Printer is Offline
Prusa needs to offer a self hosted cloud server. Connect is just so unreliable for me, especially in the past year and link is extremely limited.

Hiya,
Already reported and is being looked into. Checking to see if monkeys got into the wrenches, or if the hamsters need to be fed.
But reports filed, awaiting for resolve.

Maybe we need to teach the monkeys to feed the hamsters and the hamsters to fetch the wrenches.🤣

Just to give an update of the last issue with Prusa connect,
- Mitigation: We implemented traffic shedding and resource scaling to stabilize the environment and process the backlog of requests.
- Next Steps: Our specialists are conducting a full Root Cause Analysis (RCA) to identify the database trigger and implement new rate-limiting precautions to prevent similar "retry storms" in the future.

Appreciate the follow up!! Received my Connect update in the morning and it's been working perfectly after that
Just to give an update of the last issue with Prusa connect,
Service Update: Resolution of Connection IssuesSummary Last night, our services experienced a temporary disruption. We are pleased to confirm that all systems are now fully operational.What Happened The incident began with an unexpected database issue that caused a brief service interruption. As systems began to recover, a surge in automated reconnection attempts from customer devices created a high-volume traffic spike. This "retry storm" mimicked the patterns of a DDoS attack, leading to extended periods of high latency and connection failures.Our Response * Rapid Detection: Our supervising team was alerted by user reports and internal monitoring, triggering an immediate emergency response.

We appreciate your patience while our team worked through the night to restore your service.

Seems that is still unresolved. Today again the Printer Offline thing.
Strange enough, the App on the Mobile phone shows "Online" and notifies me about a finished print....

Yep, still an issue today, and has been for a year now.
lost a 12 hour print at 87% due to “g-code transfer too slow”
my internet is fine. The buddy3D camera still shows.
Prusa connect status shows “error: bug”
very cool. I was considering picking up a second core one as I have a bunch of spare parts, but I’m thinking of just selling it at this point. I am tired of these errors not being prioritised by Prusa.

@plastic-golem and @kgapp
I would suggest contacting support as they can ask for your account details and then it could be submitted to the connect devs to look into your accounts and see what the issue might be.

RE: Prusa Connect Keeps Showing Printer is Offline
Last time I did, spent an hour or so on the phone, made numerous screenshots and the final response was: your set up seems to be o.k., only way to get it going again is delete the printer from connect and reinstall it. Did so, worked for a couple of prints and a few weeks, and then again.
So this time I did not bother to contact support, and rather deleted / reinstalled - annoying, in particular as the print history in Connect is lost, but takes only a couple of minutes vs hanging around with support for hours and coming to the same result.

RE: Prusa Connect Keeps Showing Printer is Offline
It’s really starting to get annoying. I've bought my MK4 on February 2024, upgraded to MK4S on March 2025, but I've never seen Prusa Connect work properly.
I can upload models, I can see the camera feed (Prusa Buddy3D Camera), and most of the time (unfortunately not always) I receive notifications on the iOS PRUSA app. But the displayed printer status is OFFLINE. This is true in an external browser, in Prusa Connect within PrusaSlicer (MacOS and Linux tested), and in the iOS app. Very rarely does it show the status as ONLINE for a few minutes, but it’s always only in one of the mentioned places — never in all of them (web, slicer and iOS) at the same time.
And in the last few days, I’ve started getting iOS notifications saying “printer requires attention.” But when I go to the printer, everything is perfectly fine—the printer is printing, and there’s no problem shown on the display either.
PS: I've posted the same report on GitHub https://github.com/prusa3d/PrusaSlicer/issues/13935#issuecomment-4243255633 as it was the best "issue" I was able to find
