My Channels instance stopped working today, and when I logged into the admin area, I had a banner at the top that said my subscription had expired. My card was billed for it, so I clicked the "Check again" button to no avail.
Looking at posts here in the forums, I disabled all firewalls and adblocking. That has not made a difference. Another post I saw said that uninstalling, deleting the folder, and reinstalling worked for them. I tried that, and now I am stuck at the log in to authorize my server instance.
The relevant entries in the log file are:
2022/03/19 21:33:09.209289 [ERR] json: cannot unmarshal number into Go value of type string
2022/03/19 21:33:11.254789 [AUTH] Error during oauth: oauth2: cannot fetch token: 401 Unauthorized
Response: {"error":"invalid_grant","error_description":"The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client."}
2022/03/19 21:34:16.864759 [ERR] json: cannot unmarshal number into Go value of type string
2022/03/19 21:36:44.731713 [ERR] json: cannot unmarshal number into Go value of type string
That last line also showed up every time I clicked "Check again" before I reinstalled Channels.
Currently, no firewall is active and adblocking is also disabled.
