Could not connect to Redis at 127.0.0.1:6379: Connection refused

regarding this Rspam filter stats have reset

I tried:
redis-cli -s /var/run/redis-rspamd/rspamd --scan --pattern BAYES_* | xargs redis-cli del

But the server answers with:
Could not connect to Redis at 127.0.0.1:6379: Connection refused

What could be the cause and how to fix it?

Sincerely, Marko

Ps.:

yes, but I really want to reset my bays filter because a lot of wrong spam classifications by my user

But the reset procedure doesn’t work.

read carefully what you pasted and you will see your typo…a clue look at redis

I like that you are trying to draw my attention to something specific. But I obviously have tomatoes on my eyes.

it makes sense, we use a specific database path, you have to adjust it

Just now it works well

yes I can: Rspam filter stats have reset

Where is the best place for me to do this? …new article? …expand an existing one?

in the useful command like you found the tip to reset it, a real howto needs a place but tiny command needs a tiny place.

But you can do it like you want, do a new place and drop a link in the useful command, same for me

@stephdl done: https://wiki.nethserver.org/doku.php?id=userguide:manual_training_of_the_bayes_filter_rspamd#manual_training_of_the_bayes_filter_rspamd

please review the how to.
