Lo0 traffic blocked

[Actionhenk]

I was looking in the firewall log and im seeing alot of blocks by default deny rule with interface lo0 source 172.57.97.50:443 (this is the internal pfsense IP) to 172.57.97.50:<random port="" here="">.  I have openvpn, but no one connected. I disabled squid, disabled 127.0.0.0 outbound nat rule but the block still shows up..I guess this is the loopback interface. What could be causing the blocks ? I dont understand why. Does someone know what is happening ?

Thanks!</random>
