IPv4 Access Not Working (Tunnel/Applications)

Hey,

Have setup tunnel access to one of my self-hosted applications on a rapsberry pi, restricted access via IP, works fine with Dynamic IPv6, obviously the issue is it’s dynamic.

IPv4 is static, have entered that in but it doesn’t seem to be working/allowing access? It’s probably nothing but figured worth mentioning that when I input the IPv4 in to cloudflare application rules, it does seem to be adding a “/32” at the end after I hit save?
