Cannot saved documents with HTTPS setup

Hi, I deployed the latest image (with NextCloud) and modified the setup to get HTTPS but since then the documents cannot be saved. screenshot from 2018-08-09 16-41-08 Not really sure what can cause this but I think it's my Nginx configuration as follows: `user www-data; worker_processes 1;

error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid;

events { worker_connections 1024; }

} ` Furthermore here the logs I'm getting when opening and closing an OnlyOffice document. Regarding the fact I'm getting some 301 code I think it's, even more, a lead towards Nginx dockers.log

Any advice is more than welcome.

Thanks a lot in advance
