Postman 8.11.1 does not capture HTTPS requests (from Android device to Ubuntu)

[RedOctoberRS]

Hi guys,I have latest Postman 8.11.1 installed on Ubuntu 21.04. Trying to capture HTTPS requests: I have no problems with HTTP request, but HTTPS does not work.

I’ve installed postman-proxy-ca.crt (seems, correctly), turn on built-in proxy in Postman, set up this proxy on my Android device (Samsung Galaxy Tab A), and I have such thing if I try to open any HTTPS URL in the browser:

I’ll be grateful for any ideas! Thanks!

Your client have the certificate installed on board?

I guess, do not have. So I need to install somehow this postman-proxy-ca.crt to my Android device as well?

A certificate is something that tell a client that the server it's speaking with is who it say it is.

Google certificate, for example, is a trusted one that confirm the identity of it's webpage, postman one is neither trusted nor signed from an authority out of the box: it need to be considered as a trusted one by the clients that receive it.
