Hi
I have a big problem with my MacbookPro. Many websites is blocked with sec_error-unknown_issuer, and the certificate Cisco Umbrella Secondary SubCA fra-SG. It is Facebook, Onedrive etc. It is the same in Safari, Chrome and Firefox. The problem came for day to day without doing any installations. I have tried to delete all certifications from Cisco, but the problem is still there. Any suggestions?
