I can't make it work on my DO VPS, Ubuntu, softether

Please follow the below template, it will help us to help you!

Expected Behaviour:

Well, i have a Digital Ocean VPS, which i've installed softether on it (i followed a tutorial on a blog, cause i've not an expertise on linux. Though i can say i'm using somehow on different hardware for 17 years) and only use it for softether. Recently, i wanted ad blocking at server level and found pi-hole. But i can't figure out how can it work. Documentations here unfortunately is not detailed and i need step by step guidance. I have executed pinhole -d command. Hope someone can help me

Actual Behaviour:

Ad blocking and trying to open web interface doesn't work for me.

You should be able to use some of this detailed VPN guide on our wiki: GitHub - pi-hole/pi-hole: A black hole for Internet advertisements
You also need to move the VPN server off of port 53, as that is needed for dnsmasq.
