Hi,
I am using a Mac with BigSur version 11.2.3. I used to work with paraview remotely and it worked fine, since I installed Xquartz. Now, when I try to connect paraview gives the following error: Could not receive tag . 1010580540 Endian handshake failed .
And in my remote I can see the following error message:
/usr/lib/ssh/ssh-askpass: line 47: /usr/lib/ssh/x11-ssh-askpass: No such a file or directory.
Also you could try nomachine for remote connection instead of ssh + x11. The drawback is that the free version allows only one user on the remote machine.
