Auto restore via continuum-restore often failing

[usbhub]

I recently updated to ubuntu 20.04 and it seems that the continuum-restore setting is now only working about 50% of the time. Even before it would fail on occasion but now it seems almost every other time I have to manually restore with ctrl+b, ctrl+r . It may be unrelated to the ubuntu upgrade but something seems to have caused a failure/race condition to happen more frequently on my machine.

My .tmux.conf:

set-environment -g TMUX_PLUGIN_MANAGER_PATH ~/.tmux/plugins

# List of plugins
set -g @plugin 'tmux-plugins/tpm'
set -g @plugin 'tmux-plugins/tmux-sensible'

set -g @plugin 'tmux-plugins/tmux-resurrect'
set -g @plugin 'tmux-plugins/tmux-continuum'

set -g @resurrect-capture-pane-contents 'on'
set -g @continuum-restore 'on'

# Initialize TMUX plugin manager (keep this line at the very bottom of tmux.conf)
run -b '~/.tmux/plugins/tpm/tpm'

I also have this issue. I had to comment out @continuum-restore 'on'.

My case is a bit different as TMUX exits with information about Connection refused
