Jitsi works locally, but not over the internet

[mekler22]

I am using version stable-10184 Installed on synology nas via docker (linux) 4 containers created: docker-jitsi-meet-jicofo-1 docker-jitsi-meet-jvb-1 docker-jitsi-meet-prosody-1 docker-jitsi-meet-web-1

After editing the .env file a couple of times, and correcting these items (http port 8000 is taken by portainer so had to change it):

# Exposed HTTP port (will redirect to HTTPS port)
HTTP_PORT=8001
# System time zone
TZ=Asia/Singapore
# Public URL for the web service (required)
# Keep in mind that if you use a non-standard HTTPS port, it has to appear in the public URL
PUBLIC_URL=https://xxx.xxx.xxx:5008 (masked, and also used reverse proxy and opened the external port and port forwarded it in my router to the internal 8443 port)
# Media IP addresses to advertise by the JVB
# This setting deprecates DOCKER_HOST_ADDRESS, and supports a comma separated list of IPs
# See the "Running behind NAT or on a LAN environment" section in the Handbook:
# https://jitsi.github.io/handbook/docs/devops-guide/devops-guide-docker#running-behind-nat-or-on-a-lan-environment
JVB_ADVERTISE_IPS=x.x.x.x (internal lan ip),x.x.x.x (external static ip)

So when I try to access via my chrome browser in windows, I can create and join rooms without an issue. But when I installed the jitsi app on my android phone and tried joining or creating a room - I keep getting disconnected.

Please help. I also cannot see any issues in the logs.

Debugging on Android is a tad more difficult, so let's start simple: does it work using a desktop browser, over the internet?

[mekler22]

No. As I mentioned, it works on a desktop browser, but inside the LAN. I have not tried it on a desktop browser from the internet (meaning another location). I did try it from my android phone outside my local wifi network, and it keeps disconnecting, as I said.

x.x.x.x (external static ip)

Have you setup the port forwarding from this IP address on port UDP 10000 to this: address x.x.x.x (internal lan ip)?

And make sure there is no firewall blocking it.

x.x.x.x (external static ip)

I have now. I will test tommorrow. thanks

And make sure there is no firewall blocking it.

I already opened the relevant ports, in the firewall as well as in the server

Okay, so current development is as follows: I can open and communicate on jitsi, but only via the external address, and only in a web browser (any other option causes disconnection). Can you help so my jitsi android app (at least) works (it is set to my external address)? or even my internal address works to make calls? Thanks.

Are you using a valid certificate?

Are you using a valid certificate?

It is having a problem getting a certificate from letsencrypt. it just goes through all 30 steps and times out and again and again.
