Look like this bug has only happened on Catalina on 10.15.7 because I could not reproduce this bug on Big Sur 11.4

Insomnia app is in the foreground and Proxyman in is Background, but the data is still updated properly.

I will try to reproduce it on Catalina on my Parallels app 👍

Sorry but I could not reproduce this bug on Catalina 10.15.7 too 🤔

As you can see on the video (Dropbox link):

Proxyman is in the background
Terminal / Google Chrome is in the foreground (Focus)

=> When I make a request, Proxyman still updates the request/response properly without focusing on it.

https://www.dropbox.com/s/rppqbwzq3gbomgy/1.mov?dl=0

Just wondering: Does it happen all the time?

Can you test again with this scenario:

Open Proxyman and put it in the background as your screenshot
Open Terminal and run

curl -x 'https://httpbin.org/get' --proxy http://localhost:9090

Enable SSL Proxying on this domain
Run the script again and see whether or not Proxyman updates the data

Thank you in advance 👍

@NghiaTranUIT I saw this ticket and had a few minutes, so figured I'd give it a try since I'm on 10.15.7. I wasn't able to reproduce the issue using your test steps.

I had to change the command to curl -x 'http://localhost:9090' 'https://httpbin.org/get'. Running yours kept giving me an error: "curl: no URL specified!"

Also, OP mentioned it was when getting 400 response codes, so I also tried curl -x 'http://localhost:9090' 'https://httpbin.org/status/400' which still worked as expected. I also tried both breakpoints and scripting to force the response to 400, but it still updated normally.

Thanks for your support @crankygeek 🌮

I'm unable to reproduce the bug with a different scenario too. I guess we have to wait for the response from @AnthumChris 👍

Hi everyone, thanks for looking into this. I'm not sure what may have caused this, and it hasn't been affecting my workflow anymore. I've gotten into the habit of closing Proxyman before initiating my corporate VPN, so perhaps there was an issue with the VPN not playing nicely with others.

I'm happy to close this since it's not easily reproducible.
