In addition, nginx reverse proxy provides SSL. I did not see any error when pressing F12 on the web page. I have no idea how to deal with this problem. I hope to get some suggestions

Do you experience any problems while viewing or sharing the screen?

NepPure commented 2 months ago

Yes, after sharing the screen, the other subnet client opens the browser and nothing happens

jmattheis commented 2 months ago

please show the full log with only two clients in one room. Does https://app.screego.net work? What content does the variable SCREEGO_TURN_PORT_RANGE have. Is SCREEGO_EXTERNAL_IP an ip in the subnet?

NepPure commented 2 months ago

SCREEGO_TURN_PORT_RANGE is 50000-50200. SCREEGO_EXTERNAL_IP is an ip in the subnet.

PANEL_APP_PORT_HTTP=5050
PANEL_APP_PORT_TURN=3478
SCREEGO_EXTERNAL_IP="198.18.7.16"
SCREEGO_TURN_PORT_RANGE="50000-50200"

Full logs

The domain name resolution address in the log is subnet IP 198.18.7.16

https://app.screego.net

It's not work.

Because it is a self-built server in my VPN network, I hope to use TRUN. However, I can't see any problems from the logs. The websites and services built by other clients in the VPN can indeed access each other normally.

NepPure commented 2 months ago

In my VPN networking mode, all subnet IPs can directly access each other. Do I not need STUN or TRUN and can I connect directly like in local mode?

jmattheis commented 2 months ago

Turn shouldn't be needed when the clients can see each other. Could you try using https://docs.docker.com/compose/compose-file/05-services/#network_mode network_mode: host for the screego service?

Could you try two desktop clients. The mobile device could be the problem.

jmattheis commented 2 months ago

Could you try out the newest version. I've made the logging more verbose by including the actual payload. In there you should see the *ice message. They should include the ips from the subnet. for me it looks like this. See e.g. 192.168.178.2 which is the ip of one of my clients.

Have you tried using two desktop browsers clients for the sharing and receiving on different devices

It works with two PCs! But it's strange, I can use it with my phone in a pure LAN, but not with VPN.
