Desktop: Cannot login to NC 14 RC1

[aleho]

With the lastest build of 2.5 trying to log in to a RC1 NC 14 the client is stuck without an error message.

This happens using app passwords and also "normal" login (with 2FA though).

The log seems to indicate that somewhere a protocol string is missing after successful login:

Could be related to #592

[aleho]

I traced the missing protocol string back to an event (?) where apparently the host is used instead of the full URL, so I quickly checked whether the patch below would fix my problems, but apparently the request is not authorized.

[aleho]

624 didn't fix this problem for me.

Please let me know if you cannot reproduce my setup and need an environment to test against. I'd be happy to provide you with a test account.

[aleho]

Oh, and for the sake of completness: Access via WebDAV works in Nautilus.

[rullzer]

@aleho could you provide me with test credentials to your instance?

[aleho]

With pleasure! How can I contact you?

[rullzer]

@aleho o sorry I missed your notification. roeland at nextcloud.com works :)

[rullzer]

So I tested with the credentials you send me.

I can login just fine using the normal flow. With and without 2FA.
However I can reproduce the manual apptoken issue. I'll see if I can fix that.

[rullzer]

Fix for the apptoken is in https://github.com/nextcloud/server/pull/12177
I'll make sure that gets backported as well.

@aleho can you still reproduce it with a regular login?

[aleho]

I can confirm that regular logins work now, tested on two systems.

[rullzer]

Glad it works now.
