Mattermost-6.7.0-linux-amd64 NGINX Proxy

Hello, I installed mattermost-6.7.0-linux-amd64 on my “Ubuntu.20.04.3 LTS focal” server.
I use NGINX.1.14.0 for many servers, which is configured as a proxy with folder’s and IP filter,
but unfortunately that doesn’t work with Mattermost, I’ve tried everything I could find on the internet.

I am new…

----------- NGINX .1.14.0 Begin Mattermost Konfiguration ------------ 02,06.2022 --------------------------

server {

listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name test999_com; ( _ is a dot ) (new user can only 2 link show )
… ssl at so on…
