Error: Hestia crashes on API v-add-domain

Hello, just installed Hestia to play around and here is the problem:
My data is:

data = {
        'user': 'admin',
        'passwrd': 'my_password',
        'hash': 'access_code:blablabla',
        'returncode': 'no',
        'cmd': 'v-add-domain',
        'arg1': 'admin',
        'arg2': 'test.com'
    }

And this request just crashed Hestia with no logs in any logfile.

Obviousely, I messed up auth params, now I don’t even undersand how to restart it :face_with_head_bandage:

Did you try to create a new user and add a domain under that user?

May be this can give more information on what is hapenning.

Tried again from admin and second user - keep recieving 401
IP is in whitelist, data is correct, host answers 401 and reboots for like 10 min each time
