Now the service does not start.

We're working through the sloppy submissions to the port and plugin now and hotfix as we progress.

Okay. Thanks Franco. I removed the default_min_port=1024 and friendly_name=OPNsense UPnP IGD & PCP from the configuration file and the service started. I'm not sure if this will negatively impact anything. I'll wait to hear back from the Opnsense team.

I followed the instructions in the Reddit thread that Franco posted and the issue was resolved. This issue has been resolved.

Both port and plugin should be hotfixed now.  May take a bit for all mirrors to pick it up.


Cheers,
Franco

I'm actually getting a different set of errors.  Not sure if the patch addressed this:

Actually removing the STUN host address fixed this issue.
