Answer 1

I'm not using rocket.chat but in case you can manipulate your app, this could be one way to make it work:
I see, your have your own internal server and you have to install a root certificate on your phone to connect to your server.
If so, you have to do the following things:
Add android:networkSecurityConfig="#xml/network_security_config" to the application tag in your Android Manifest and create the corresponding file to:
app/src/main/res/xml
This is the Content of the network_security_config.xml file:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<debug-overrides>
<trust-anchors>
<certificates src="system" />
<certificates src="user" />
</trust-anchors>
</debug-overrides>
</network-security-config>
So your App knows to use the installed certificate, otherwise it will use the platform Default.
I have to say, this problem appears to many developers, so there could be other solutions, like I found with jitsi-meet.
But this is the way it worked for me.
Hope it helps.
