WebRTC not working from web-ui dashboard

[calimansi]

It was working yesterday, now it won't. If I type in the url for each camera through webrtc, it works fine. HLS works fine through the web-ui.

Weird.

[JA16122000]

Can confirm, WebRTC is not working for now.

[mrlt8]

This should be fixed in v2.1.7!

[calimansi]

That was quick!!! You guys are supposed to wait until I get impatient then fix it.

Anyway, thanks. Yep, it is fixed.

[Mystichrome]

This appears to still be happening for me in 2.1.7. Exact same behavior as calimansi described. Started in the middle of the day on version 2.1.6. I later upgraded to 2.1.7 after seeing this, but still having an issue getting WebRTC working from the web-ui. going into individual camera's works fine.

[mrlt8]

There were some breaking changes to the way WebRTC was initialized with the backend MediaMTX, but it should have been resolved with 2.1.7.

Do you see anything in the browser console? Could you try another browser?

[Mystichrome]

I'm currently using brave browser, but have tried chrome and firefox. Same issue. In Chrome and Brave I'm seeing these errors for each camera:

webrtc.js:95 Sending offer X.X.X.X/:1 Access to fetch at 'http://X.X.X.X:8889/front/whep' from origin 'http://X.X.X.X:5000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: It does not have HTTP ok status. :8889/front-yard/whep:1 Failed to load resource: net::ERR_FAILED webrtc.js:71 Error: TypeError: Failed to fetch at Receiver.createOffer (webrtc.js:97:9) at webrtc.js:87:51 onClose @ webrtc.js:71

Haven't had the chance to check firefox console.

[mrlt8]

Hmm. The CORS issue should have been patched in MediaMTX v0.23.2. Are you using the latest docker image?

[Mystichrome]

I use the latest tag when pulling, yes. The web ui shows v2.1.7. Docker inspect:

[mrlt8]

could you see if v2.1.8 fixes the cors issue?

[Mystichrome]

I'm still seeing the cors errors in 2.1.8 unfortunately. Is there possibly anything I missed that I need to do after the upgrade? I've tried restarting the connection to cameras, rtsp simple server, and clear cache and reconnect from the gui. Tried doing an incognito browser session as well.

Got a chance to look at firefox's console, similar message concerning cors:

15:29:11.419 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://X.X.X.X:8889/yard/whep. (Reason: CORS request did not succeed). Status code: (null).

[calimansi]

I'm running this on an x86 machine.

[andrew-suh]

I'm running into this as well on a docker container. I can use HLS, but webRTC fails completely. `

[mrlt8]

was it working in a previous version?
