Unable to connect TestComplete 12.0 due to Azure DevOps will stop accepting TLS 1.0/1.1 connections

Hey Everyone

We are using Test Complete 12.60 and Today we are unable to connect VSTS project and After doing some analysis we found that Test Complete uses TLS 1.0

Azure DevOps will stop accepting TLS 1.0/1.1 connections from Jan 31st, 2022. Please check our blog post for more details.

Could help us how to solve this problem.
