Hi There I’ve installed rocket.chat on Ubuntu 18.04.3 LTS. For SSL I’ve installed NGNIX as a Reverse Proxy with the following Config: # Upstreams upstream backend { server 127.0.0.1:3000; } #HTTP to HTTPS Redirect server { listen 80; listen [::]:80; server\_name [mydoamin.com](http://mydoamin.com); return 301 https://mydoamin.com$request\_uri; } # HTTPS Server server { listen 443; server\_name [mydoamin.com](http://mydoamin.com); ``` # You can increase the limit if your need to. client_max_body_size 200M; error_log /var/log/nginx/rocketchat.access.log; ssl on; ssl_certificate /etc/nginx/certificate.crt; ssl_certificate_key /etc/nginx/certificate.key; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # don’t use SSLv3 ref: POODLE location / { proxy_pass http://backend/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forward-Proto http; proxy_set_header X-Nginx-Proxy true; proxy_redirect off; } ``` } So everything works fine on the browser with rocket.chat and SSL as well. The Problem ist I cannot login to rocket.chat via the android app. It keep saying the URL is wrong eventhough I can open rocket.chat via the smartphone’s browser. On IPhone I’m able to login to Rocket.Chat via the App. Does anyone know what the problem is? Thanks for your help! ---

I’ve managed to fix it. The problem was NGNIX as the Reverse Proxy. It has for some reason problems with websockets. I uninstalled NGNIX and installed Apache as my reverse proxy and followed the instructions here: [https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/](https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/) And after that everything worked fine. I hope this helps someone else that run into this problem. ---

Hi I have same problem too. my revers proxy server is Apache and I have been configured it with best practice that was wrote in RocketChat Docs. when I use my URL that same as [https://chat.company.com](https://chat.company.com) I see “Invalid URL or unable to establish a secure connection…” on **Android Mobile App** but this URL work on browsers and Windows App correctly! If I use [http://chat.company.com:3000](http://chat.company.com:3000),my Mobile Android App connect to server correctly. I couldn’t understand whats that. Thanks, ---

I´ve got the same issue than you. I got to solve it adding the intermediate certificate in the /etc/nginx/certificate.crt file (refering the nginx session in the official how to [https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/](https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/) ) Copy and paste it after the certificate data of the certificate file. The apache approach works because it adds the intermediate certificate in the procedure. ---
