Hi there, I’ve been noticing a small issue when using the --force-offscreen-rendering option over a remote connection.

This is my connection string:

`ssh $SSH_USER$@$SERVER$ /usr/local/lib/mpi/gcc/openmpi3/bin/mpiexec -np $NUMPROC$ /usr/local/bin/pvserver --server-port=$PORT$ --client-host=$CLIENT$ --force-offscreen-rendering`

I use ParaView with offscreen rendering via the EGL API (VTK\_OPENGL\_HAS\_EGL:BOOL=ON). When I start a pvserver process on the server via the ParaView client, I get the following error output on the client:

```
Waiting for client...

Connection URL: cs://<myserver>:<myport>

Accepting connection(s): <myserver>:<myport>

Client connected.

No protocol specified

No protocol specified

```

What does “No protocol specified” mean?

I’ve checked and confirmed that the GPU is being used on the remote machine, so I can’t determine what this error message is about. Is this an issue to be worried about?

does your remote have a display, a running X server ?

It does have an X server available, but the error occurs regardless if there is an active X server running or not.

I think this is a false error because ParaView works remotely ignoring the error, but I want to make sure I’m not missing something
