Floccus uses Nextcloud's login flow which allows you to use your normal password and 2factor authentication when authenticating for floccus access. Can you try your normal credentials?

@marcelklehr sorry for the dealy,
also did not work.

Works for the nextcloud client and browser on the same device though.

FYI: Got 2FA set up with a yubikey or OTP tokens as second factor

Also of interest: Floccus from my firefox on debian (laptop) syncs to the same instance/account without any issues.

Sorry for the delay.

also did not work.

@akallabeth What happened?

Logs from instance:

@b-m-f That error looks like a server side issue. Logging in with login flow shouldn't trigger an exception.

Sometimes you need to log in twice. Nextcloud has a bug regarding that

Nice catch indeed, but that does not resolve this issue (it also does not work with normal passwords except with the older version mentioned, where I can log in perfectly)

@akallabeth I couldn't wait for the new release, so I just went and edited the ClientFlowLoginV2Controller.php on my docker container. I was able to login with app password afterwards. Quiet easy if you have access to the instance.

@marcelklehr Tangential but if the login could utilize Android's built-in accounts similar to what the Notes and Talk app do (using accounts registered from the main NC app), it would be ideal.

@mottech20 many thanks for your hint to edit the file directly in Docker.
It brought me a step further, but actually to the next login issue.
For anyone running into same trouble where Nexrcloud authentication was not succeeding this might help you.

I found that using the Floccus app the login process referred to a http login page, so removed https.
When using the Chrome extension my login did not succeed after Zugriff gewähren.
This fix was solving the issue, run following command in your nextcloud docker instance:
docker exec -it -u www-data NAME_NEXTCLOUD_CONTAINER bash -c './occ config:system:set overwriteprotocol --value="https"'

This is sadly not possible due to incompatible technologies used :/
