Documentserver refused to connect

[jonas740]

I am going crazy trying to install Onlyoffice into Nextcloud.

I am using latest nextcloud, swag, cloudflaredns, redis, mariadb in a docker compose.

i can reach the welcomepage by entering my subdomain adress but when set up in nextcloud and i try to open a document it just takes me to a white page where it says documentserver.mydomain.com refused to connect.

I tried pretty much everything i can think of but i cant get onlyoffice to run with nextcloud.

I have had it working in the past. Linuxserver.io have helped me check the settings and it should work but it does not.

Is there something i am missing here or what. Subdomain is set as CNAME as it should be and container is named documentserver

Any help would be much appreciated.
