    This is a perfectly normal connection error that occurs when we misspell the server name, the instance is not running, there is a firewall in the way etc. And every time we run into this, we have to our troubleshooting. We can not just dump the error message in a forum - because how could other people know what may be wrong in our environment?

    Here is an article with further troubleshooting tips.

    Hi @mohammed alshami

    In what operation did you encounter this error? Can you describe it? This helps narrow down the scope of troubleshooting.

    As a supplement, here is a highly discussed thread for your reference.
