Hi Bosco, I’m not sure I understood your issue. AFAIK Rspamd UI requires a trailing slash in the URL to work properly. Did you add a trailing slash to the Rspamd UI URL? E.g.
This has problems:
https://<HOST_IP>:980/rspamd
This may work instead:
https://<HOST_IP>:980/rspamd/
At least in NS8 this is the requirement. For NS7, I don’t remember.
For completeness, this is the relevant NS7 manual section Email — NethServer 7 Final (trailing slash not documented )
