Piwik login redirects to wrong url

I have installed the piwik on guest8.example.com but somewhat I misconfigured during the installation that the login url is guest8.example.org therefore when I perform login it gets redirected into guest8.example.com how I can change this misconfiguration with the correct one?

I am using the docker image from https://hub.docker.com/_/piwik/ before 9 months and I has this info:

In other words I can access the both the global.ini.php and config.ini.php via a volume.

So far I unsuccessfully tried to put the following setting into :

[General]

login_logout_url = "https://guest8.ellak.gr"

I also have the following [General] settings:

[General]
force_ssl = 1
proxy_client_headers[] = "HTTP_X_FORWARDED_FOR"
proxy_client_headers[] = "HTTP_CF_CONNECTING_IP"
proxy_client_headers[] = "HTTP_CLIENT_IP"
enable_trusted_host_check = 0
salt = "ed8c6f4bd17e41e1b90bfe0f7664771f"
trusted_hosts[] = "guest8.example.org"
trusted_hosts[] = "guest8.example.org.cy"
trusted_hosts[] = "172.17.0.1"
trusted_hosts[] = "0.0.0.0"
login_logout_url = "https://guest8.example.org"

I can only go to panel with enable_trusted_host_check = 0 setting and manually visiting the http://guest8.example.org after a sucessfull login.
