      Description

      For the past few weeks every time I try to log on to Minecraft it gives me a message saying "Sorry, but we couldn't connect to our servers. Please make sure Minecraft is not blocked. (CertificateException: No subject alternative DNS name matching authserver.mojang.com found.)" I looked up how to resolve this problem but nothing worked at all. I made sure the Firewall was not blocking Minecraft or anything like that and it still doesn't work and that message keeps popping up.

      What I expected to happen was...:
      Log on normally

      What actually happened was...:
      A message saying "Sorry, but we couldn't connect to our servers. Please make sure Minecraft is not blocked. (CertificateException: No subject alternative DNS name matching authserver.mojang.com found.)"

      Steps to Reproduce:
      1. Open up Minecraft
      2. Login with your Username and Password
      3. Message pops up
