Thank you very much for the answer @rrwick I have checked that X11 forwarding is activated. It has been on all the time. For background info to others is here...

I have the same problem with Ubuntu 16.04.6 LTS on a cloud server. X11forwarding is set to 'yes' I have installed Qt5 (libqt5core5a, qtbase5-dev and libqt5svg5-dev), still does not work....

The same has happened a lot to me since I upgraded to v0.4.7. It is very annoying. I have also seen that returning to v.0.4.4 avoids the issue.

It did not solve the stall problem for me. I built a fresh conda environment with Unicycler 0.4.7 but the stalling still occurs frequently.
