> I would suggest contacting GitHub and Intellij. This may also be a possible firewall/proxy issue in your environment. I may be wrong here (someone else chime in please) but this is not looking like it is caused directly by git. Part of this may be the communication protocol you selected in Intellij or a TLS compatibility issue between your machine and GitHub. There are some articles at StackOverflow discussing this error that may be helpful.
