Question
Why do I get the Chat server error: Try to refresh chat now. If that doesn't work, ask your Admin to contact Zendesk... followed by a string of random letters and numbers?
Answer
The Chat server error indicates there was a recent subdomain change on the account. It's expected that live chat may experience up to two hours of downtime after a subdomain change. The error should resolve itself within the two-hour window. More details can be found in the article: Renaming your subdomain.
If you are still receiving this error and the subdomain hasn't been updated recently, see the following article to check your Chat connection: Troubleshooting your Chat connection.
