Original GitHub issue: https://github.com/ProxymanApp/Proxyman/issues/641

Proxyman version? (Ex. Proxyman 1.4.3)

2.7.0

macOS Version? (Ex. mac 10.14)

10.15.6

Steps to reproduce

Reset all certificates.
Run iOS simulator (After that we can see many requests which our device send to server but OFK we can not read them without certificate.
Install certificate on iOS simulator and so on.
After the restarting I don't see any request anymore.

I've been struggling with this situation more than one month and can not resolve this trouble.

Expected behavior

Should be working fine. It's worked nice two-three months ago.

Screenshots (optional)

@CaramelHeaven If you don't see any traffic from iOS Simulator, it means the HTTPS Proxy doesn't point to Proxyman Local Server (port 9090) anymore. Maybe some app reverts it.

Can you help me to check Proxy in Wifi -> Advanced -> Proxies Tab. Are HTTP and HTTPS Proxy enabled?

If you're using any VPN app on macOS, iOS simulator traffic doesn't show too. Please turn it off.
If it still doesn't work, can you verify that you've installed the Helper Tool in Proxyman Preference -> Advanced -> Helper Tool?

I tested on the Alamofire sample project with iOS Simulator, it works fine.

@NghiaTranUIT Thanks for reply.

Checked
Checked
Helper Tool did not installed. After that my requests showing. Okay, this problem was solved. But now they all contains SSL Handshake Failed :)

Okay, let's run the simulator. We seeing that all requests failed. Go to Certificate -> Install certificate on iOS Simulators -> click on buttons -> Reset simulator -> Try to open simulator again -> Failed. I checked again the certificate on iOS - it disappeared.

I have tried again my scheme described above and it doesn't work. I think after running the simulator my certificate gets deleted and I need to install a new one over and over again.

I also tried to completely reinstall Proxyman but that didn't help.
Curious enough.

As u can see below I checked all suggestions and restarted simulator but if I close the "certificate window" and try to open again the 2 and 3 steps refreshed to default value

@CaramelHeaven thanks for getting back.

It's correct behavior because there is no official way to know whether or not the open Simulator is installed with a Proxyman certificate or not.

Just wondering: Can you help me to verify that you can see https://google.com in your safari mac? Just make sure you've installed and trusted the certificate correctly.

Here is the step:

Open Safari on Mac, visit https://google.com
Select the google.com request from Proxyman app -> Click Enable SSL Proxying on the Response Panel
Reload the safari again and see if you can see google.com HTTPS response

Look like you're using External Proxying on the right bottom toolbar. Can you turn it off?
Look like you're selected, Document Filter. Please select All

There are many reasons why you got SSL Error. Here is the troubleshooting https://docs.proxyman.io/troubleshooting/get-ssl-error-from-https-request-and-response

Glad to hear that 👍

I will improve the Helper Tool detection if it detects the HTTP Proxy doesn't change and the tool hasn't installed yet. It will prompt the user to fix it.
