External IP connection on port 80....

I'm running servioo on my mac and with a packet scope a can see an active connection coming from an external ip to the serviio app on port 80. I've tried blocking serviio on my firewall and I can no longer use the server but the connection persists. I've tried stopping the server and the connection persists.
I changed my password on my remote settings even though I know it isn't connected through port 80.
It's an ip for a computer in Switzerland.
Any thoughts?
