Error in log file

[redaktorn 23]

Dear Friends,

For some reason i get exactly the same eror in my logg-file every 10 minutes (exactly).
My server is functioning good. Except maybe a few second long pauses with my external users (not often and sporadic).
(Which quickly reset them selves)

Do I need to worry about this error?

Here is the error:

hi, that's coming from the automatic port mapper. You can ignore it or disable it in emby server network settings. If you disable it, then you may need to manually setup port forwarding in your router for remote access.

OK - Good to know - Thanks 
(I have already manually setup the ports in my Router, so I will ignore it)
