Not sure whether 1.0.36 should have also fixed the problem about the Referer header not being picked up by ffmpeg

It was 1.0.38 I wanted to know status of for you issues - not 1.0.36

With respect to the ffmpeg picking up the Referrer / Referer headers - a change has been made to the latest Emby Server beta 4.9.0.36 which has just been released

Please try it and let me know

Thanks

Thank You. I understand this is expected to be resolved in 4.9.0.36 beta. I have passed on the logs

My initial problem seems to be fixed in the latest beta build (I'm using 4.9.0.37 beta) of Emby, with M3U tuner 1.0.38.0. Thanks!

Yes the change for ffmpeg to pick the Referer / Referrer came in 4.9.0.36 and we now send both Referrer and Referer as some providers are looking for Referrer.

Thanks for confirming the fix

If this is working on vlc with the same m3u file, I would suggest using wireshark or tcpdump to look at the http requests and responses and when finding the one the one that gets a 403 forbidden on emby, to look for the same request that goes out when using vlc and then compare the two requests checking the http headers

You can use wireshark filters like filter on http to make it easier to view the network requests going out and responses

With debug logging enabled on emby server (settings / Logs / settings) you should be able to see details of the request getting a 403 response

I am afraid you will need to troubleshoot this yourself initially. IPTV Smarters Pro may work very differently. Are you trying IPTV Smarters Pro with the same m3u file

Do you expect VLC to be working?

Best for troubleshooting is to use wireshark and see how the http requests are being made for the applications that work and those that do not 

Does vlc get a 403 as well or a different issue

Yes in IPTV smarters PRO it works if i upload the file of the m3u and if i paste the url of the m3u. In VLC appears "no se puede reproducir"

In VLC, what happens when you select Media / Open File / R:\Emby\TV-65430471_playlist.m3u

Best to compare the requests using tcpdump or wireshark between emby and IPTV Smarters when specifying the same m3u file

Hi. 

I have the same problem with my M3U....

[cchavagu 2]

The error that appears in VLC is "Su entrada no puede abrirse:"

Hi, you need to change the User agents setting and put this: IPTVSmartersPro

[cchavagu 2]

It works!!!! Thank you Dius

I have S8K as an IPTV provider, if I use any server they provide I get the above error but if I use IPTV Editor to get a shortened URL emby will accept it. I still get the 403 forbidden error.

Tried with a beta server on VPN as well but no change.

I put IPTVSmartersPro in the user agent header first and then the referer as well but nothing changed.

The non shortened url work fine in other IPTV apps.

Maybe you need to find specific values to make their hosting sites happy?

[lorac 118]

I suppose that's a possibility although it doesn't rank that high on my list. 

So for now since Live TV is of no use to me how do I remove it from the library list...

Have you tried removing the TV sources ?

Emby Server Settings / Live TV / Setup tab - TV Sources, clicking the ... for each TV source and then selecting Delete
