Sabre DAV Exception

[ClepToManix]

Hallo,

we had an bug in our nextcloud installation. Since we have updated nc those errors are still appearing. In nextcloud app running on android the "new account page" always pop up on this devices. The only solution is, to deaktivate network, delete the account and add them again.

thanks for your help

Moving then 🏎️

[nextcloud-android-bot]

GitMate.io thinks possibly related issues are #3573 (Remove exception), #2982 (Add provider Exception), #3133 (fix exception handling), #85 (Auto-uploading pictures fails sometimes), and #1450 (Sabre\DAV\Exception\BadRequest: expected filesize 1024000 got 552960).

[tobiasKaminsky]

Hm. First I thought it would be the same like #3623, but if it is working after deleting the account, it cannot be the same.

@ClepToManix do you use any special things? 2FA? LDAP?

[ClepToManix]

No, nothing. After deleting it works for a few days. Actually the only solution to remove the accounts which are affected from this bug.

[tobiasKaminsky]

After deleting it works for a few days.

Do I understand you correctly that a working account fails after some days, and after removing the account locally on the device, it works again for only a few days?

Yeah, right.

Yeah, right.

@nextcloud/server-triage this sounds to me as if somehow the app tokens get removed/invalidated?

[ClepToManix]

I dont know.
In Error log i found this one:
Object of class OCA\GroupFolders\Versions\GroupVersion could not be converted to string at /var/www/kwolkemk/apps/groupfolders/lib/Versions/ExpireManager.php#126

Maybe this error connected with the main error

[ClepToManix]

Updated to Nextcloud version 15.0.5. Still the same error

[blizzz]

@icewind1991 perhaps groupfolders related?
