linux ssh x11 bash

I'm attempting to set up X11 forwarding over SSH from my Debian 11 machine to a remote CentOS 8 server, but I keep working with the behavior 'X11 connection rejected because of wrong authentication.' I've ensured that both machines have X11 installed and configured properly, and I'm using the `-Y` flag with my SSH command. My SSH config file (`/etc/ssh/sshd_config`) on the CentOS server includes the line `X11Forwarding yes`. However, I still see this behavior when trying to launch graphical applications like `xload` or `gedit`. I have also verified that both `xauth` and `xorg-x11-xauth` are installed on the CentOS machine. Running `echo $DISPLAY` after connecting via SSH shows that the `DISPLAY` variable is set to `localhost:10.0`, but I'm still unable to run any graphical applications. I've tried restarting the SSH service and even rebooting the server, but the scenario continues. Here's the SSH command I’m using for connection: ```bash ssh -Y user@remote-centos-server ``` And I checked my `.Xauthority` file on my Debian machine with: ```bash ls -la ~/.Xauthority ``` It seems to be there and correctly owned by me. Can anyone suggest what might be going wrong or how to troubleshoot this further?
