Can't connect to self signed certificate https server using Android app

android
#1

hello,
I deploy a rocketchat server on my vps server.

I created a self signed certificate with Custom Root CA and configured it in nginx config file.
(https://rocket.chat/docs/developer-guides/mobile-apps/supporting-ssl/)

And I configured a SSL Reverse Proxy using nginx.
(https://rocket.chat/docs/installation/manual-installation/configuring-ssl-reverse-proxy/)

Because I don’t own a domain name,I use IP address to visit rocketchat server.For example,https:// xxx.xxx.xxx.xxx

Now I can visit rocket server successful with web browser and desktop app.
I can’t connect to server with android app using https.(https:// xxx.xxx.xxx.xxx)
Error message is “An error has occurred while checking your server version,please try again.”
But I can connect while using http.(http:// xxx.xxx.xxx.xxx:3000)

Android apk is downloaded from github release.And I installed version3.3.0.
(Rocket.Chat.Android/releases/download/v3.3.0/app-play-release.apk)

Rocketchat server version is 0.74.3.
Android version is 8.0.0.

Can you please help me to resolve this problem?
Thanks.
