Behind vpn and dns. No connection

[hedztrem]

What are you buying from ovpn.com?  You should not need to buy anything.  Your router is hosting an OpenVPN server and the OpenVPN client is free from Google's and Apple's app store.  In your router there should be prompts to download the OpenVPN config for your server that you use on your phone.

I'm buying the options to hide my wan ip. More privacy. And also my isp tries to block some streaming services. Thats working better thrue a vpn like ovpn, nordvpn. 

But if i understand you correct i can set up this for free? In my router and then maby my ddns with jellyfin can work?
However its important not to have install on every Phone,computer etc. Because i have a formuler z7 that is need of this
