Sorry I can’t answer your question directly, but I was very surprised by numbers you showed.
With standalone proxy I have lot more connections in hour than your screenshot shows for a day:
2022/09/24 14:56:03 In the last 1h0m0s, there were 84 connections. Traffic Relayed ↑ 506 MB, ↓ 230 MB.
Do you have public IP address? If not, it may explain low connection count.
