Antman executable gone missing after reboot

Hi,

I rebooted my antsle as couple of containers were too slow. After that I was not able to access the interface at :3000 port.
ssh'ing into server - i ran : systemctl status antman 

It states that executable in not there /usr/local/bin/antmand

If i try to run antman-upgrade, that also fails with error

ValueError: No JSON object could be decoded

* Failed to install antman license:

If the antMan service is gone and antman-upgrade fails, the most reliable fix is a fresh install of antMan 4: antman4.antsle.com. Back up your antlets first.
