Can’t link to Prusa Connect

After setting up PrusaLink on my Raspberry Pi 4B 2GB and Prusa MK3S+, I cannot link it to Prusa Connect. At the end of setup (I followed the instructions here), I click Save printer and link with Connect | NEXT. Then I get some 500 error from Prusa Connect. So I reflashed my Pi and tried again but I got the same error. I looked at the Settings page on my Prusa Link, but there are no instructions on how to link to Prusa Connect if it fails during setup. 

Anyone smarter than me know how to get it connected?

RE: Can’t link to Prusa Connect

Hi, it does not fail for me, so let's try and see if we can find any differences between our setups.

What did you name your printer and the location it's in?
What version is your PrusaLink and the printer's firmware?
Anything else that you can think of that could be different between your setup and mine? Maybe a special character in the wifi ssid, or any other value we might have not expected?

Thank you and sorry it's broken for you

Thanks for your response Tojik!

WiFi is basic, no issues connecting to that. I'm not sure what could be different. I have a very bare bones setup right now with no mods since I wanted to make sure this stuff would work first. I enabled SSH (password auth), setup the Pi username and password, and disabled telemetry with the Imager when I setup the Pi.

Actually, I think I found the answer! Unfortunately, Prusa Connect requires telemetry to be turned on. Not great. I found the line below in the syslog file.

Aug 27 11:50:02 horton interesting_logger[593]: WARNING: Was[DEBUG]: Connect isn't configured -> no telemetry {_log():97}

Reflashing the image with telemetry on fixed the issue!

Wait what? Which telemetry? That message just says we won't send stuff like hotend temperature to Connect, because there is no connect configured. What telemetry did you enable/disable that it had such an effect?

Found the telemetry checkbox, nope. I don't have it on either :/ weird.

I enabled telemetry in the settings menu on the Raspberry Pi Imager! It is generally on by default, but I disabled it the first times.

Yea, i have it disabled, worked for me. I still think it must have been something else, but glad it works now
