RegEx does not work should be simple

System.Exception: Cannot create CMOperator.An existing connection was forcibly closed by the remote host at CMOperator.CMOperatorConnection..ctor(String ihost, String iuser, String ipassword, Int32 iport, String iCMName, String iLoggerConfig, Boolean iEnablePing, Boolean iPersistConnection) at ExtensionManagerDLL.Class1.ProvisionImpl.GetPbxConnection(String pbxName)

I want to grab all of the information from Cannot... and just get rid of System.Execption. I dont know why my regex wont work, RegExr says that it will.

rex"Exception:(?<Message>.+?Name)\)"

Try:

... ¦ rex "System\.Exception:(?<Message>.*?Name\))"

It would also help to append an expression segment right aftert the capture group that would only match the string that follows what you want to extract.
