Anyway to fix this now or are we premanently locked out of this means of runnning remote apps. I think SSH allow forwarding on the client side
No need for 'xhost +' on the local. Check if X-forwarding is enabled in remote's sshd_config. Also use '-C', speeds up things considerably even in LANs.
It is on the ssh client (x forwarding)
X11 forwarding reques failed on channel 0
Cannot open display "default display"
Re-read my post. It must be enabled in remote's sshd.
