Hey everyone,

I’m here because I can’t reach my server after following process [https://docs.mattermost.com/install/config-tls-mattermost.html](https://docs.mattermost.com/install/config-tls-mattermost.html) :  
**Listen Address** setting to `:443` .  
**Connection Security** setting to `TLS` .  
**Forward port 80 to 443** setting to `true` .  
`sudo setcap cap_net_bind_service=+ep /opt/mattermost/bin/mattermost` done  
**Use Let’s Encrypt** setting to `true` .  
Restart the Mattermost server for these changes to take effect.

My config.json :  
“SiteURL”: “mattermost.mydomainname:443”,  
“WebsocketURL”: “”,  
“LicenseFileLocation”: “”,  
“ListenAddress”: “:443”,  
“ConnectionSecurity”: “TLS”,  
“TLSCertFile”: “”,  
“TLSKeyFile”: “”,  
“TLSMinVer”: “1.2”,  
“TLSStrictTransport”: false,  
“TLSStrictTransportMaxAge”: 63072000,  
“TLSOverwriteCiphers”: [],  
“UseLetsEncrypt”: true,  
“LetsEncryptCertificateCacheFile”: “./config/letsencrypt.cache”,  
“Forward80To443”: true,

It’s ok when i’m restarting my mattermost service, but on a web browser, nothing works.

In fact, it’s the same problem as the following topic : [[SOLVED] Unable to connect to Matermost server when secure connection is Enabled](https://forum.mattermost.com/t/solved-unable-to-connect-to-matermost-server-when-secure-connection-is-enabled/4359)  
But in my situation my “Forward80To443” is set to “true”.

Did i miss something ?

Many thanks in advance. 🙂

Hi @Hindrik-H,

What error messages are you seeing? Are you using Nginx?

Thank you for your help but It doesn’t change anything…  
Maybe i’ll try with nginx as a proxy
