I tried for a few days to get the custom Service working with absolutely zero success.

I am trying to block all access to this domain, period, as we are getting a lot of phishing and spam from this domain.

Sample URL, that im trying to block

https://cloudflare-ipfs.com/ipfs/bafkreiag5g3bm57a5fickxd5gqwc3mcspxxpaslgnabymwzpxpyst773t4?filename=INBOX-Login.html#support@computer-facilities.com


Is it possible to advise how to get this working properly?

    If the browser is not using a VPN or proxy you should be able to block it.

    Have you applied the Content Filter to a policy control rule? Have you tried the DNS Content Filter too?

    Block UDP 443 from LAN to WAN

    QUIC uses UDP port 443 instead of TCP 443 the way Content Filter works for TCP 443 is by SNI in the clear but if a web site uses QUIC Content Filter can't work by blocking this it forces the browser to use TCP 443

    also run this in console

    debug content-filter https-domain-filter cache flush

    OK did a system wide test, it seems the custom rules do not work, the content filter profile is working just fine, its the custom side that is not!

    Try adding *cloudflare-ipfs.com to the forbidden websites.
