Nextcloud version (eg, 20.0.5): 25.0.3
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04.1 LTS
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.52
PHP version (eg, 7.4): 8.1.2-1ubuntu2.10
The issue you are facing:
Can’t embed another nextcloud as external storage with credentials of an account that has 2FA enabled. Getting HTTP error code 401 (see below). As soon as I disable 2FA for the account, mounting the second nextcloud (or a folder therein) works without problems.
Shouldn’t this be possible with a browser window popping up asking me to provide a TOTP code, similar as with, say, the Nextcloud Windows client, where I can also connect accounts with 2FA this way?
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- go to admin settings → external storage
- try to connect to a second nextcloud using username and password of a given account
- if the account has 2FA enabled, this will fail and a red icon instead of a green one will show
