The URL in the error message should have a DNS entry that points that domain to the Raiser's Edge Web Service (REWS) server.  AFTER verifying that DNS for this domain is correctly configured, this error indicates an issue with the network or the environment that is hosting the NetCommunity web server. If the NetCommunity web server producing the error is not hosted by Blackbaud, please contact your IT staff or whoever manages that environment.
