Discourse Integration app don't redirect me back to Nextcloud and don't work

Nextcloud version (eg, 20.0.5) : 29.0.0
Operating system and version (eg, Ubuntu 20.04) : Ubuntu 20.04.6 LTS
Apache or nginx version (eg, Apache 2.4.25) : Apache/2.4.41
PHP version (eg, 7.4) : 8.2

I am trying to connect Nextcloud with Discourse by Discourse Integration app. This is my configuration in Discourse:

And in Nextcloud:

When i click on ‘Connect to Discourse’ i am redirected to Discourse:

But if i click ‘Authorize’ i get an error, i am not redirected back to Nextcloud and i don’t have any changes in Nextcloud


Error:

’ because the scheme does not have a registered handler.

What am i doing wrong?

P.S.
If that’s important i have Discourse SSO app installed and working properly.
