Why is VPN required outside NL

I have two services one used in Portugal and the other I use in NL and while travelling. A few years ago I could use the service any where in EU without a problem. Now it will not work without a vpn connected to NL.
I assume it’s something world is doing as I have another iptv provider at that works without a vpn.
Can anyone shed some light on this?

I’m using my iPad with XCIPTV and in NL XRS4900

Hello, without knowing what service you are referring too, this is hard to say. But if you are unable to connect with a provider in another country, it’s very likely the ISP is blocking connections to that specific provider/serverprovider/IP-address range. e.g. is blocking the IPTV services.
