Whenever I send hi to my Google Chat friend, I receive an error message. You cannot message and the friend's name. Why?

I believe your friend blocked you in Google Chat. Verify it with him.

Is it the correct Google Chat ID?

Yes, Rejeena, the Google chat ID is correct. I guess Thomas is right about it. But not sure though

.

Thomas's assumption is correct. The other person has blocked you.

The only solution is to reach out to the person and ask him to unblock you. You might need another Google Chat ID or Gmail to reach him. It is the only solution, sorry kiddo.

So, am I right?

It is a classic user block. Sorry buddy, your friend blocked you.
