This seems to have something to do with IPv6 - you can disable it by doing the following:

1. Go to View **Network Connections**

I've been working with a repo in Azure for months without any issue, but recently started getting this error intermittently when I try to update my remotes or push/pull:

OpenSSL SSL_connect: Connection was reset in connection to dev.azure.com:443

If I keep retrying, it will eventually work. No idea what is causing this.

Things I've tried:
- Updated Git
- Turned off firewall
- Tried on a different computer with no issues

fatal: unable to access 'https://dev.azure.com/xxx': OpenSSL SSL_connect: Connection was reset in connection to dev.azure.com:443
