NTOPNG login seems broken

[tre4bax]

I am trying to use NTOPNG for the first time in a while and it will not let me login.

I followed the instructions that come up through the login page and various other bits of internet advice that essentially add up to these three

redis-cli set ntopng.prefs.local.auth_enabled 1

redis-cli del ntopng.user.admin.password

redis-cli SET user.admin.password ea847988ba59727dbf4e34ee75726dc3

Iv'e tried the with the service stopped and with the service started following with a refresh but still the login prompt rejects me.  The login itself will not even allow me to enter the admin password for the router as the button stays faded (I think it is too long for the web front end).  I am using NTOPNG with Https and that was working fine, however I have upgraded to 21.7 since the last time I tried to use this.

Anyone got any advice on things to try?  Will removing it from the box and putting it back help or will the setup be retained anyway leading to no change?
