Error in logs, Error HttpClient: Error ProtocolError

[holdestmade 11]

I just noticed this is appearing in my log every 10 minutes, could you let me know what it means and if I need to do anything to fix it ?

 

For info, the IP address xxx.xxx.x.xxx is my router.

 

Thanks

Disable automatic port mapping if you're not using it.
