Xquartz Error Message in Terminal

Hi guys.

I'm trying to access to my university data server and since I need to visualise some .nii data and open MatLab, I need xQuartz to run on the Terminal provided by Apple Utility.

The problem is the following error message has been making me crazy for weeks:

Warning: untrusted X11 forwarding setup failed: xauth key data not generated

My previous line was simple as the this:

dhcp-128-202:~ myname_mysurname$ ssh -X server@stuff.it

I suspect macOS Catalina can be a possible reason of the current problem, but still looking for a solution (I also downloaded iTerm as someone in previous posts has suggested, but same result)!

Thanks in advance

MacBook Air 13", macOS 10.15

Hi etresoft, thanks for your prompt answer.

Actually I was a little bit suspicious about this solution once I read what was discussed in this forum about your idea:

I'll try your solution anyway.

Did you see this post?

Normally I'm not a fan of Stack Overflow answers. I would rather figure out what is really going on. But in cases like this, the problem is that there is something setup funky on the server and you are unlikely to ever be able to figure out what that might be. Trial and error using the experiences of other Linux users may be tedious, but will probably work eventually.
