Unrecognized FaultException when Connecting to RemoteAgent

How can I troubleshoot the following error message in the dotTrace Profiler Configuration dialog?

Unrecognized FaultException: code Receiver, prefix Server was 
unable to process request. ---> Unable to open f

I have a RemoteAgent configured and running on a server, firewall port 9000 open.

Attempting to connect to it, I specify the IP address, port, and endpoint and I get the message above. That is it...it ends with the letter "f" and I'm not sure what it is referring to. I checked the logs, unfortunately, this is all I'm getting:

There doesn't seem to be any information on the server either. All I see in the event log is the following, which is logged on startup of RemoteAgent but makes sense as it likely doesn't want itself to be profiled:

The profiler has requested that the CLR instance not load 
the profiler into this process.

There are no other log files or artifacts that I can find.

Other info:

  • I'm on Windows 8.1
  • dotTrace version is 5.5.4
  • Server is 2012
  • All apps run with admin privileges

I have been able to connect to other RemoteAgents on other servers. Don't know what the missing piece is here.

Re: Unrecognized FaultException when Connecting to RemoteAgent

James,

 

There are also RemoteAgent logs, located in the %TEMP%\JetLogs folder on remote machine. They could be more helpful.

 

From what I can guess so far, it is likely failed to access the binaries cache directory, located at %ProgramData%\JetBrains\Profiler\RemoteAgent\SysToolsCache.

 

Could you, please, check log files and the cache path above.
