I was able to verify your rDNS via dig:

dig -x 45.79.125.193 +short
koi.webxy.xyz.

The command syntax that you used is now also resolving with your domain:

dig +short ptr 193.125.79.45.in-addr.arpa
koi.webxy.xyz.

It can take some time for DNS changes to propagate, which is likely why you weren't seeing the expected response when you initially ran the commands. There's some more information available in this Community Questions post that explains how long DNS changes can take to propagate. You'll typically see your changes go into effect within an hour, but full propagation can take between 24 and 48 hours.
