Mattermost unreachable

Troubleshooting

I’m having this problem

Please check connection, Mattermost unreachable. If issue persists, ask administrator to check WebSocket port.

This is my NGINX File.

server { listen 80; server_name xx.xx.com; return 301 https://xx.xx.com$request_uri; } server { listen 443 ssl spdy; server_name xx.xx.com; ssl_certificate /etc/letsencrypt/live/xx.xx.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/xx.xx.com/privkey.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers 'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-AES256-SHA:ECDHE-RSA-DES-CBC3-SHA:ECDHE-ECDSA-DES-CBC3-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA'; ssl_prefer_server_ciphers on; location / { proxy_pass http://xx.xx.com:8065/; proxy_read_timeout 90; proxy_redirect http://xx.xx.com:8065/ https://xx.xx.com; } }

I also used the NGINX config going off Mattermost install guide. But it kept timing out and when accessing it direct through the IP I had the same message.

Can anyone advise? Everytime you post a message you get the unreachable message.

Thanks.

Hi @Law,

I apologize for the very late response. To use NGINX as a WebSocket proxy you need to specify the follow:

location / {
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
}
