Description

Follow up from #4624, a similar error occurs when using fuzzy learning on the rspamd web ui.

How to reproduce:
Go to the rspamd web ui, click on "Scan/Learn". Just enter anything as mailsource (it doesn't matter what was entered), and press "Scan Message" and then "Upload Fuzzy". An error occurs:

If I use the browser debugger, i can see that the result of the post request to https://mail.mydomain.de/rspamd/fuzzyadd is "404 Not Found".

If I however enter https://mail.mydomain.de/rspamd/fuzzyadd directly in my browser, I get "Unauthorized" which for me means, it is reachable.

Not sure why this happens and rspamd cannot connect to /rspamd/fuzzyadd.
It was like this since I was using mailcow, which was around the april-22 version of mailcow.

Logs

There are no log messages corresponding to this error - I checked the output of every mailcow docker container.

Steps to reproduce

1. Go to the rspamd web ui
2. click on "Scan/Learn"
3. enter anything as mailsource (it doesn't matter what was entered)
4. press "Scan Message"
5. press "Upload Fuzzy"

This error still exists, just because someone doesn't post in a thread doesn't mean the error doesn't still happen.
As far as I can tell the fuzzy stuff in rspamd doesn't even work

The error is wrong (rspam's fault) the page doesn't actually 404 error. They're giving you a JSON response with the 404 error code..

actually silly me, this is rspamd's fault @baderas you should post it there

It may be a mail cow configuration issue? @MAGICCC

gonna guess it is this one https://github.com/mailcow/mailcow-dockerized/blob/master/data/conf/rspamd/local.d/fuzzy_check.conf
