Support mTLS Client Certificate Authentication
Feature Request
Would be great if Yaak supported mTLS client certificate authentication. For my use-case it would make sense to have this configurable either globally linking each cert to a specific host (similar to how postman does it) or maybe per-environment.
This is live in the latest beta! I was only able to do minor testing around it so please let me know if you find any bugs.

I’m getting the following error on a certificate request. I am having trouble to understand what is wrong and what is missing from the error message. Public requests (that do not require the client certificate) to the same API/Server seem to be handled just fine. Is this an issue in Yaak or did I do anything wrong in my configuration?
Extra info, when I use a PFX instead (this comment) of seperate key and cer files (screenshot in previous comment) I get a different error:
