Error PortMapper: Error in GetSpecificMappingAsync/DeletePortMap

[notuxnobux 9]

I've recently started getting this error from clients playing content remotely.

What happens is that after ~30 mins of playback, their video streams pause for an undetermined period of time. After a while, they resume, or if the user steps back a few seconds it resumes too.I finally was able to get my remote user to tell me whilst it was happening, and grabbed the following from the log:

I'd love some assistance here. Thanks.

I've just realised that my port mappings for the local/remote ports didn't match my port forwards in my router.  Of course I didn't realise this until I asked for help... *sigh*.

Anyway, I've made the changes and will re-test to see if that resolves the issue. I'll report back with my results.

You could just forward ports manually and disable Automatic port mapping/uninstall Port Mapper altogether (which IMHO should be the derault setting anyway, having it disabled by default).

It is actually part of the installer but yes is enabled by default unless you opt out during the install process.

I know, hence the statement.

Good call. I'm forwarding the ports manually in my router anyway, so I'll uninstall port mapper, as I know the ports I want to use.

Thanks!

Really no different having Remote access enabled by default and not in the installer.  But user will say why does it not work out of the box.  As not having portmapper enabled requires manually port forwarding.  So user will say why does it not just work.

But yes PortMapper is problematic on various setups.

[GrimReaper 3999]

Easily solvable by few lines of helper text during install process. And we've both seen our fair share of logs flooded with related and unrelated Port Mapper issues, with latter even being worse.
