more problems with 21.1.7_1 update; can't start ntopng or redis

[RobLatour]

When I tried to do the 21.1.7_1 update this morning the system hung.   I rebooted but it was still hanging.

Following the advice of other the posts here today and I cleared my browser cache, after which time the update reports having being completed. 

Now when I check for updates the system says it is up to date. 

However, now both the ntopng service and the redis service as shown as red / stopped on the dashboard, and neither can not be restarted. 


Ntoping log says:

2021-06-22T10:38:04   ntopng[94041]   [Redis.cpp:150] ERROR: to specify a redis server other than the default   

2021-06-22T10:38:04   ntopng[94041]   [Redis.cpp:149] ERROR: Please start it and try again or use -r   

2021-06-22T10:38:04   ntopng[94041]   [Redis.cpp:148] ERROR: ntopng requires redis server to be up and running


The redis service option to enable it is checked, but it is not running.

I assume once I can get redis working again, ntoping will follow.


Any advice would be appreciated.

ok - so I went into Services - redis - General Tab and then clicked the Reset button, after that Redis started.

I was then able to start ntoping.

However, I then signed in via the web interface, and it appears all the names I had previously assigned my hosts have been lost :-(
