Problems while setting up Keycloak


I’ve installed Twake and tried to connect it to my existing keycloak instance, but I am unable to login.

First I got /internal/services/general/v1/server 502 (Bad Gateway)
and after I restartet Node, PHP and Nginx I get the default login page and can even create an account, although I disabled the internal auth in the backend config.

The current Parameters.php looks like this: PasteServer

Did I miss something or is there a known problem?
