inconsistent behavior in port mapper causes freeze during playback

[turpentine 17]

 

Hello team,

i do not not know what you have done with the last versions of emby, but port mapper seems to do inconsistent network playback

could you please check why sometimes you are asking the upnp router to delete port mapping during playback ... ?

have a nice day, each time i see port mapper errors in embyserver logs, the playback stops on my samsung tv.

is there a way to desactivate port mapper in emby inside user interface ? it makes me mad. thanks a lot. i will use static port mapping instead as a workaround ...

Devs will need the who server log but yes there should be an error for each event.

Personally think this plugin should just go away or disabled by default and require users to do port forwarding as it shall never work all the time on all routers/environments.

is there a way to export all the logs via user interface in one click ? port mapper was working fine before for me, so it means that someone has done new change in this plugin.

There is only one active log "embyserver.txt" Restart or Rotate starts a new one saving the old one for 3 days. 

But since you are on Synology it is not that easy to just go to the Log folder you can only download each log via the Settings-Logs.

here are my logs, it is very painfull to see such a mad behaviour, it seems to stop playing every 20 min for example at around 23:04 or 23:24 28 dec 2022

PS : @Happy2Play private joke, port mapping plugin may be usefull in ipv4 non CGNAT stacks,  but with ipv6, portmapper should be desactivated if a user wants. port mapping is useless with ipv6 home routers

@Luke could you please ask a dev to look at this ?

Hi Luke yes i still  have the issue. found a temporary workaround by removing the A DNS ipv4 record in my domain name provider in order to Force connections in IPv6. 

When i activate back ipv4. The emby port mapper plugin every 20 minutes Ask my router via UPnP to delete/re-add the listening ipv4 TCP port.

Quite weird could you please fix port mapper in order not to do that during playback ?

@Lukehave you Seen my logs ?

Port Mapper is a user removable plug-in.

Thanks but it would be a lot better to fix it. I think a lot of user issues in this forum Is caused by it. It is very Smart to ask the external public ipv4 to delete his own listening port during playback. Very Smart plugin.

What kind of router do you have?

[turpentine 17]

A classic FTTH home router provided And branded by the Telecom company with ipv4/ipv6 fiber And 4 ethernet ports. IT has UPnP And WiFi 5. 

In ipv4 mode Emby plugin seems to Ask to delete the forwarded port to my lan Emby server every 20 min. Of course in IPv6 there Is no port forwarding. UPnP Is not used in IPv6 :). So in IPv6 there Is no playback issues due to bad networking software decisions.
