Hi there, How can you "BLOCK ACCESS TO PROXYMAIN.IO FROM PROXYMAN APP" 🤔

Do you mean that using app like AdGuard or Little Snitch to block all connections from specific app?
Or you mean the Black List Tool in Proxyman?

If the answer is YES, you're using Little Snitch to block all connections from Proxyman, so you couldn't access the Internet is correct behavior, since Proxyman acts like Proxy server before going to the Internet

Technically, here is how Proxyman works:

Proxyman opens the local server at 9090, and act like Man-in-the-middle.
Proxyman overrides the HTTP/HTTP Setting in Network.prefPane from you computer
All traffic from your device will go through Proxyman 9090 and then forwarding to the destination server.
Similar approach like Charles Proxy and Fiddler. There are no traffic to Proxyman.io server at all (Unless License Validation and Get Update build APIs).

Can you help me to double check the HTTP Proxy Setting? Is it point to 9090?

I try to "Block Proxyman.io" by using Self Control.
I confirm that:

I couldn't access proxyman.io and https://proxyman.io/v1 at all (Self Control blocks it)
Opt out all Analytic and Crash Report from AppCenter In Preference
Open Proxyman
Able to connect the Internet as usual.

I'm not sure how to reproduce your step 🤔

Sorry for not responding sooner...

I confirm that you're right!!! In my hurry I overlooked the network settings and got overzealous about non existing security issues!

Greate work!

Cheers and apologies once more.
