jobber stopped working all of a sudden.

[MUSAID P P (RA2133002011010)]

It was working fine from last November until day before yesterday. 

I have installed jobber in my Ubuntu 20.04 and the system is operated remotely as a server. Thus, jobber was used for daily simulations since cronjob was not working properly. But now,  I am getting an error saying "Jobber doesn't seem to be running for user aoml.

(No socket at /var/jobber/1000/cmd.sock.): stat /var/jobber/1000/cmd.sock: no such file or directory"

Can somebody help me in this regard?
