Bug: refreshToken - Error: | 400

[lohrm-stabl]

Sometimes the light just does not work. Othertimes it works fine. Sometimes it's after a running for 24 hours, sometimes it happens after 5 minutes. Right now, restarting does not even help.
I run the latest main with a custom Azure APP.

The log then shows:

HTTPS] Method: POST, Response code: 400
refreshToken() - Error:
refreshToken()
[HTTPS] Method: POST, Response code: 400
refreshToken() - Error:
refreshToken()
[HTTPS] Method: POST, Response code: 400
refreshToken() - Error:

And the light lights up in red (turning, with 1/4 LEDs on).

Hi @lohrm-stabl,

I couldn't reproduce this issue so far. Something seems to go wrong when refreshing the token. Unfortunately you can't see details in the logs. So I published a new version v0.18.5 that has extended logging in this case. You may try with this version and then we may see why this fails.

Greetings

I had this running for quite some time with extended logging but did not notice any issues. So I close this issue for now.

Just came across the HTTP 400 as well. The extended logging revealed that it was because I hadn't used the device for >90d. Hence, the refresh token had expired in the meantime.
I had to wipe the flash and set up the app from scratch. Forcefully putting into AP mode and running through the login procedure might have helped as well; didn't try.
