PrusaConnect printer has shown "offline" for several days....
Prusa Mk4 (with MMU3). No changes to network environment. PrusaLink still seems to work, but PrusaConnect does not. This has persisted for several days, and across reboots of the printer. I have one of the camera setups from the Prusa blog a few weeks ago, and that's not showing up in the PrusaConnect window either. Directly accessing the ESP32 camera works fine. Seems to me to indicate there's something going on on the PrusaConnect server side?
RE: PrusaConnect printer has shown "offline" for several days....
If the printer is not sending a status via Prusa Link to Prusa Connect then it is impossible to see the camera images on the Prusa Connect, even if esp32 is correctly sending images, this is a known limitation.
I suggest checking PrusaLink details - directly status on the device which runs it (whenever it is a firmware or raspberry pi device).
Double check the connectivity to the ethernet/wifi on the devices.
You may need to reset wifi and readd it again.

I have the same situation. Nothing has changed in the network environment, but for several days Prusa Connect shows the printer as offline many times (meanwhile, the printer shows "error - net fail" in the menu). Sometimes it works fine, the printer is online, then offline again at random intervals. The WiFi connection is stable, Prusa Link always works well.
