Jitsi call disconnect after dial in android

Question

I am using openfire and I wanted to add voice and video call feature in my app. First I have made installed two plugins ofmeet.jar and offocus.jar.

Then I have installed lets encrypt wild card certificate in openfire. ex:

/snap/bin/certbot certonly --dns-route53 -d example.com,*.example.com

Installed those generated certificate in openfire by admin dashboard panel.

created a subdomain openfire.example.com to point with VPS IP address. however my FQDN is example.com.

added code in android to start meeting

try {
JitsiMeetConferenceOptions.Builder options = new JitsiMeetConferenceOptions.Builder()
.setServerURL(new URL(“https://openfire.example.com”))
.setRoom(“testroom”)
.setWelcomePageEnabled(false);

        JitsiMeetActivity.launch(OutGoingMeetingInvitation.this, options.build());
        finish();
    } catch (Exception ex) {
        ex.printStackTrace();
    }

Am getting error in android phones that am disconnected and reconnecting in seconds. In android studio I am getting error

E/JitsiMeetSDK: [features/base/lib-jitsi-meet] Failed to load config from https://call.example.com/config.js?room=call_1606192562839 Error(AbortError){“message”:“Aborted”,“stack”:“Error: Aborted\n at anonymous (index.android.bundle:135:6514)\n at anonymous (index.android.bundle:135:7422)\n at call (native)\n at dispatchEvent (index.android.bundle:126:5676)\n at value (index.android.bundle:121:5993)\n at value (index.android.bundle:121:5621)\n at l (index.android.bundle:135:6840)\n at call (native)\n at dispatchEvent (index.android.bundle:144:5676)\n at value (index.android.bundle:143:1114)\n at anonymous (index.android.bundle:876:490)\n at anonymous (index.android.bundle:399:500)\n at apply (native)\n at value (index.android.bundle:50:1280)\n at apply (native)\n at value (index.android.bundle:37:3685)\n at anonymous (index.android.bundle:37:841)\n at value (index.android.bundle:37:2939)\n at value (index.android.bundle:37:813)”}

Please help me to solve this issue.

The issue may be because of External ports. Enabling UDP port in server resolved this issue for me, in your server make sure below ports are enabled,

• 80/tcp for Web UI HTTP (really just to redirect, after uncommenting ENABLE_HTTP_REDIRECT=1 in .env)
• 443/tcp for Web UI HTTPS
• 4443/tcp for RTP media over TCP
• 10000/udp for RTP media over UDP

https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-docker

with Ubuntu

• 80 TCP - for SSL certificate verification / renewal with Let's Encrypt
• 443 TCP - for general access to Jitsi Meet
• 10000 UDP - for general network video/audio communications
• 22 TCP - if you access you server using SSH (change the port accordingly if it's not 22)
• 3478 UDP - for querying the stun server (coturn, optional, needs config.js change to enable it)
• 5349 TCP - for fallback network video/audio communications over TCP (when UDP is blocked for example), served by coturn
