AwesomeMiner is a brilliant software and it is a must to monitor and control your miners, but you need to understand how to use it, otherwise, if there exist any rule with the wrong conditions -- it would cause more issues.
I can help you check the rules and check the logs to see what triggers the reboot, i'd need a PC with anydesk on it, or, you could just read the documentations of the software and once you are familiar with it you can do yourself.
Also, one way to go about this would be to use mass config on vnish firmware to change the password of all miners, once done, awesomeminer won't be to control your gears, in fact, it is pretty risky to keep the default web and SSH logins, you must change them anyway, disable SSH and change the web password.
