Hello,
first at all - thank you very much for this super project!
We started testing Mattermost on a dedicated machine trying to authenticate with our Gitlab-Server on another machine.
After successful login in Gitlab after click on “Login with Gitlab” Gitlab redirects to Mattermost. The Message there is:
“We couldn’t find the existing account”
Its the same logging in with a new Mattermost user as with an existing user in Mattermost.
Both sites are encrypted. Mattermost has a nginx-proxy:
server {
listen 80;
#server_name mattermost.our.site;
return 301 https://mattermost.our.site$request_uri;
}
server {
listen 443;
server_name mattermost.our.site;
ssl on;
ssl_certificate /etc/nginx/ssl/our.crt;
ssl_certificate_key /etc/nginx/ssl/our.key;
ssl_session_cache shared:SSL:1m;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
client_max_body_size 4G;
location / {
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
#proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Proto "https";
proxy_set_header X-Forwarded-Ssl on;
proxy_set_header X-Frame-Options SAMEORIGIN;
proxy_redirect off;
proxy_pass http://localhost:8065;
}
location /api/v1/websocket {
proxy_pass http://localhost:8065;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
Where should we continue to investigate?
Thank you!
