Following 20.7.4 upgrade redis and NTOPNG will not start

[sparticle]

I need some help with this implementation.

Following a 20.7 upgrade earlier I cannot get redis or ntopng to start. Log is full of these lines. If I reboot and watch it start then redis connection fails on startup of opnsense server.

Did you set a password for redis?

Did you set a password for redis?

Was working perfectly before upgrade. There is no password set in the Gui that I can see.

What was the previous running version? 20.7?

[sparticle]

I don't recall. Whatever it was late September when it was last updated.

I'm on 20.7.4 and can start it successfully.

Maybe you have to reset Redis Cache?

[sparticle]

I had to remove the redis db and then reset the service. After that redis started then I could start ntopng.

cd /var/db/redis
rm redis.rdb

Restart redis service from gui
Restart ntopng service from gui

Seems to be up and stable.

Hope this helps someone else.

Hi,
is there a timeline for an upgrade/update to ntopng 4.2.0?

[mimugmail]

This depends on FreeBSD upstream maintainer

I had this same issue, had to delete /var/db/redis in order for redis to start.

THere's also a reset button in OPNsense UI
