My question: We have an api endpoint (https) which when tried from postman, we get response but we see an error which says " Unable to verify the first certificate ". Same API endpoint when open in chrome/edge browser , we see no issue with certificate and its shows valid. Can you explain why its showing invalid in postman?

Details (like screenshots):

How I found the problem: unit testing the apis

I’ve already tried: nothing so far.

Unable to Verify First Cert Issue - Enable SSL Cert Verification : Off

Hi All, I have googled this like mad, and am still getting the same issue. I am submitting requests, but tests throw up the warning " Unable to Verify The First Certificate". Upon Googling, i have double and triple checked that: File > Settings > Request > SSL certificate verification = OFF [image] and have also made sure that this is not overridden in “Settings” for the tests [image] But i still get: [image] Any ideas?
