Connect connection gets lost while printing

I've got two MK4S - one is native, the other a MK4 that got upgraded.

When i print something they will eventually appear offline in connect although network is fine on the printer... This happens throughout several FW revisions over the last year...

RE:

Same happens here with my Core One - and Prusalink also loses connection.

Furthermore I get a "No suitable storage found" when trying to upload prints to the printer after some successful uploads - when that happens it takes a couple of days and then all of a sudden I can transfer again for a few times - only to have it all repeat over again. And Yes - I have tried with other USB sticks.

BTW I am connected via ethernet (but the same applies when I try on WiFi) 

Firmware: 6.3.0

I have the same issue with my brand new Core One. Prusa Link (Local Network) works, but in Prusa Connect it is offline. Even the attached Buddy Cam presents an old image (30 min ago).

Same connection issue here with my CORE One.  

It will be connected for 5-10 minutes and then go-offline for 15-20 minutes and then be online 5-10 minutes.  This happens regardless if it is printing or momentarily idle.  Perhaps a server scaling issue?

RE: Connect connection gets lost while printing

I will dig out this issue as I'm observing the same problem with my Core One. Printer is randomly going to offline and I do not se any pattern why. I have now print set for 26h, printing is in progress however printer is randomly offline and online. The same issue is with buddy camera. For me it look like some bug in prusa connect. And the question is: if there is any solution?

Same here, My Core One appears on/offline randomly. My Mini does not seem to behave in the same way.

There's an issue open for this behavior on Github: https://github.com/prusa3d/Prusa-Firmware-Buddy/issues/4636
