Can't send migration tool support message

Hello, i was trying to get help migration tool, but when i clicked Send i was seeing this picture from attachment.

So maybe i'll ask here:
What to do, when migration tool was stopped while working (i was connected by ssh, and lost connection, so the session, and migration tool were closed)???
In my case, it stopped at files copying with rsync. I'm not sure if it's good what i do, but i started migration tool again with resync argument (./migrate --syncjobs). Was it good idea?
Here is the migrate.log.1 last few lines:

Oh, ok, thank you.

 

I would run the migration in a screen session. That way it is possible to get back to the running migration command if connection was lost.
