No telemetry data available
PrusaLink type: Raspberry Pi Zero W
Description of the bug, including steps to reproduce (if possible):
I am seeing this 'No telemetry data available' and a blank temperature graph during a print. My test print yesterday both of these showed temperatures and fan speeds. Screenshots below.
The printer was turned off over night and turned on this afternoon, the bug started then. I have not attempted to power cycle again to fix as it is printing currently. I will do that once the print is finished and update this topic.
Update 1
Refreshing the page (F5 and CTRL F5) does not resolve the issue and if connected directly to the printer via it's local IP the temperature graph works there.
RE: Update 2
After opening and closing the page a number of times it seems to have sorted itself out. The beginning of the graphs matches up with the timestamp of the most recent CONNECT event in the logs.
The telemetry appears to be working on both the overview and the temperatures tab.
Brower version
Should have thought about this at the time but because it seems like it could be browser related I was using Firefox 91.0, I did not check any other browsers.
