NullReferenceException: at: Mono.Zeroconf.Providers.AvahiDBus.ServiceBrowser.Browse

[wpiman]

I am running HS4 AK Bond on a Linux instance. Recently, I noticed these items in my log file.

I believe I might have installed and subsequently removed a plug in that may have used ZeroConf as well. Any pointers here? I tried removing the Bond plugin and reinstalling.

It looks like you don't have Avahi installed - on Linux it's the only mDNS (Zeroconf) provider. You can disable mDNS in the plugin settings (enable "Show Advanced settings" first). I guess in the previous install you did disable mDNS, that's why you were not getting the errors. You will need to set static IP address on the Bond bridge.

Alternatively you can try installing Avahi, see the post by BuddyRayAtl

Thanks... Looks like it was installed but not running... ?!?!

I run on a Docker container... Might need to make sure it is running when the container reboots...

I do have the Bond bridge assigned to a static IP. I know I use other plugins which make use of Avahi.

So it's all good now?

BTW, I posted BETA 4.0.5.7 with a few fixes, including the BPUP warnings you have "BPUP is NOT working".

So I pulled the beta, it ran for a while, then suddenly today at 2:57 is lost its mind and my log filled up with these.... The bond website (192.168.0.203) seems reachable.

What's your Mono version? Please post output from Tools => Help.

Does restarting the plugin help?

To be fair-- about 5 hours prior to this-- my system updated its time by a fraction of a second-- and sent a whole slew of plugins to restart. I think my system might be having some larger issues that just one plugin. I did a restore an think I fixed the clocking issue.....
