Manually connect to default server

[georgc601]

So I imagine this has something to do with how our PI is configured and our remote connections are also configured, but thought I would reach out here.

When I am remote and not in the office, and connected via my VPN connection, PIConnect works flawlessly connecting to the default server and I can access data.

However, now that I am going back into the office more, I am getting access/connection issues that I cannot resolve:

Here is the error I am getting

PIAuthenticationException: Cannot connect to the PI Data Archive. Trust authentication trial failed because insufficient privilege to access the PI Data Archive. Windows authentication trial failed because the authentication method was not tried.
 
   at OSIsoft.AF.PI.PIException.ConvertAndThrowException(PIServer piServer, Exception ex, String message)
   at OSIsoft.AF.PI.PIServer.RemoteConnect(AFConnectionPreference preference, NetworkCredential credential, PIAuthenticationMode authenticationMode)

   at OSIsoft.AF.PI.PIServer.InternalConnect(Int32 numRetries, IWin32Window owner, AFConnectionPreference preference, NetworkCredential credential, PIAuthenticationMode authenticationMode, Boolean checkConnectingAsSameUser)

   at OSIsoft.AF.PI.PIServer.AutoConnect(Boolean allowDirectConnect, Boolean force)
   at OSIsoft.AF.PI.PIServer.Connect(Boolean force)

So I have tried multiple lines of code to try and connect. PIConnect detects the default server, 'sccpi3' but just can't connect.

Here is what I tried and runs, with no errors, but then I can't get data:
PI.PIServer(server='sccpi3', username='username', password='password', domain=None, authentication_mode=AuthenticationMode.PI_USER_AUTHENTICATION, timeout=None)

And it appears to tell me I am connected:
PIServer(\\sccpi3)

Internally when accessing Datalink or Processbook, we use PI User Authentication.

Any help is appreciated.

That is some weird behaviour. I'm not sure why it would work from one connection but not the other. As I only use the Windows authentication, I can not test this. Do you have a complete snippet to reproduce the error so I can at least trace which parts of the code you use?
