We haven't made any changes to our report server and all of a sudden the URL is showing as invalid. SSMS can't log into the SSRS instance. I've checked all logs on the RDBMS side and event logs at the OS...not finding a single error. Trying to access SSRS yields these errors however:
From the web: Error: The request failed with HTTP status 400: Bad Request
From SSMS: Unable to connect to server [server name]. The specified URL might not be valide or there might be a problem wit the report server configuration...etc.
Any ideas how to trouble shoot this? All setting are OOB. Services can start/restart...box has been rebooted. No errors anywhere indicating a problem.
