can't connect to janus video room

[MaxwellGumley]

I am using the build "obs-studio-x64-2.4-1-ga879afa8.exe". I installed the janus gateway on a xubuntu 16.04.2 vm.

The Janus demo server is working fine, but OBS_WebRTC will not connect to the video room. I get the error "An unexpected error occurred when trying to connect to the server. More information in the log file." The log file does not have any additional information :(

I have tried reading the documentation for Janus, and all the issues here, but I cannot find any help. I very much look forward to OBS streaming with such low latency. Thank you for all your hard work. Please see the attached screenshots and log file.

Update: I monitored my LAN with wireshark. I discovered I was trying to connect to the wrong port. I updated the Server Name field of OBS-WebRTC to ws://xubuntu16042:8188. It is still not connecting, but at least now I'm getting a 403 HTML message from the server. I have attached the resulting Wireshark log: Wireshark_OBS-WebRTC_to_Janus-Gateway_2018-08-01.zip

Update: After experimenting with the "Plugin Demo: VP9-SVC Video Room", I discovered that the websocket on the janus server is working correctly, serving port 8188. The OBS-WebRTC is not correctly handling the address ws://xubuntu16042:8188/janus, because I can see in Wireshark that it is trying to send a TLSv1 packet, and it should not be using https for a ws address.

I'm experiencing the same or similar issue. I've setup janus-gateway on my internal network and have tested that all of the provided examples are working.

I've set the server URL in OBS to ws://janusgw:8188/janus and the room to 1234 (as that's the default room in all of the examples). I am including my full OBS log for reference:

Fixed in last release (tag 2.7). Note: For now, we only support connection through WebSocket secure (wss).

I can confirm this issue is fixed. Tested with AMD Video card and Janus-Gateway server in the default 8675309 room. Thanks @Ben-cos and @agouaillard-cosmo!

thanks for taking the time to validate and report.
