@novitae Does it happen to all URLs? or just this particular https://api.myip.com ?

[novitae]

All urls

[NghiaTranUIT]

if you try to send a request over https Do you mean by using the Compose Tool?

Or just visit a website on Google chrome ?

[novitae]

Both, trying to request, whatever, everything that is redirected to https proxy fails

@novitae I tested and it's working fine.

Here is my setup

1. Deploy a Proxy server on Amazon web service, expose port 8080 with a protected Auth
2. Open Proxyman -> Tools menu -> Proxy Setting -> External Proxy Setting
3. Config the HTTP and HTTPS Proxy to my External Proxy with correct Username/password -> Save
4. Try with many websites and it works

Screenshots

• External Proxy Config

• Confirmed that my Proxy server is working, it proxies the traffic

@novitae May you share your set up?

Please ping me on Discord, so I can share with you my Proxy Server for testing.

I believe your Proxy server has a wrong config or somethings, so you get errors.
