Nextcloud Caldav / Carddav with Thunderbird TbSync - password not saved

[necrevistonnezr]

Anyone else having a problem with Nextcloud Calendar / Contacts and Thunderbird with the tbsync addon (https://addons.thunderbird.net/en-US/thunderbird/addon/tbsync/)?

I have to re-enter my Nextcloud app password generated for this specific app every single time I open up Thunderbird. I don't have anything meaningful in my Nextcloud log and there are no similar issues on the Nextcloud or Thunderbird forums...

Have you tried the addons' issue trackers?

Thanks, I have opened a ticket on github. However, I haven't seen a similar issue, neither in tbsync nor on Nextcloud or Thunderbird forums.

After some research it seems the source of the error is that the two-factor authentication in Nextcloud stopped working.

I have 2FA enabled and created an app password for caldav sync.

However, all clients show the following error: "password login forbidden":

<?xml version="1.0" encoding="utf-8"?>
<d:error xmlns:d="DAV:" xmlns:s="http://sabredav.org/ns" xmlns:o="http://owncloud.org/ns">
  <s:exception>OCA\DAV\Connector\Sabre\Exception\PasswordLoginForbidden</s:exception>
  <s:message/>
  <o:hint xmlns:o="o:">password login forbidden</o:hint>
</d:error>

This would be correct error if I used my main password - but I don't, I'm using the app password.

Was anything changed in the recent package update for Nextcloud?

Are you able to login with the app password with other clients (like say the desktop app?).

[necrevistonnezr]

The desktop app uses some kind of webauth (you're redirected to the login page of nextcloud), so I can't say.
Other clients like iOS I can't test because Nextcloud is stopped due to redis errors (see https://forum.cloudron.io/topic/2569/after-update-to-cloudron-5-2-3-redis-runs-out-of-memory)

Now that Nextcloud is running again: Yes, I can access the Nextcloud calendar via iOS and add appointments that show up on the Nextcloud web calendar.

BTW: In Cloudron, I can generate an app password for Nextcloud in the "Profile Tab" - how is that different from generating app passwords in Nextcloud itself? Is there a conflict maybe?

@necrevistonnezr They are pretty much the same feature. Cloudron's works at the platform level for all apps including nextcloud itself whereas nextcloud's will work only for nextcloud.
