Description

Since this week and for no apparent reason proxyman decided to not work anymore.
I'm using proxyman mainly on iOS simulator and currently when I launch it I'm unable to connect to the internet.

All my requests on iOS simulator and web browser have internal error as status with the 999 code.

I checked the proxyman settings and everything seems good.

General	Advanced

I have tried installing Charles proxy and I have the same issue.
I went deeper and it seems that when the Secure web proxy is checked, this is were I lost my internet connexion and I don't understand why.

Here is my proxy settings for my wifi network when proxyman is launched.

Launch Proxyman

Current Behavior

I can't have access to internet

Expected Behavior

I should have access to internet, seeing all request from my web browser.

Environment

App version: Proxyman 4.12.0
macOS version: MacOS Ventura 13.6

Your setting seems correct. I tested it on my own and it works fine.

I guess you're using a VPN app or have an Anti Virus app that is active at the same time with Proxyman ? 🤔 If yes, try to turn it off.

Some users report that Proxyman and Charles Proxy conflicts with some VPN app, such as BitDefender.

Just wondering: Can you open Google Chrome and try to intercept some website?, such as google.com

I've a VPN but it never works together with Proxyman.
So when I use proxyman, I always disable the VPN.

It seems that google.com does complete the request but it is very slow.
Some other websites does work but other doesn't and in every case it is very slow.

I've seen something interesting. It seems that proxyman is using a lot the CPU.

If you don't mind, can you try to open Charles Proxy, and check if it also happened?

Meanwhile, you can do Factory Reset (Don't check the Include User data, so your rules are safe) in the Help Menu -> Advance -> Factory Reset.

I've found the issue, it was indeed my Anti virus app (Bitdefender).
It was working fine before but it is possible that an update of the antivirus provoked this.
Thanks @NghiaTranUIT for your time.
