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

While working with a git repository in Azure and trying to update remotes or perform push/pull operations you may face an error saying,

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

In this article, we are going to show some solutions to solve the error.

Solution 1:

The error seems to be related to IPv6. When you disable IPv6, the connection will work. You need to disable IPv6 for dev.azure.com by editing my hosts-file.

C:\Windows\System32\drivers\etc\hosts

# Workaround for git connection errors

13.107.42.20  dev.azure.com

dev.azure.com's IPv4 address may change in the future. Please verify it and update as needed.

Solution 2:

• Open your command prompt and run

  tracert www.dev.azure.com

• The prompt will show

  Tracing route to l-0011.l-msedge.net [aaa.bbb.ccc.ddd]

• Next, in windows navigate to C:\Windows\System32\drivers\
• Open host file in Nodepad++ in run as Administrator mode
• Add the line and save

  aaa.bbb.ccc.ddd dev.azure.com

• Now try to perform git operations
