I have already tried to disable ssl certificate, disable proxy and set the timeout to 0ms yet nothing worked.
Any way to fix this problem i am using the latest version of postman.

Hey @supply-administrato1, this looks like an invalid server certificate error/issue but still, I would recommend going through the Github issue (though it is an open issue, you can find ample solutions. I hope one of those might work for you)
