high ping for persians

so ive been playing here for long time but since a couple months ago iran and ovhcloud which is where warmane host the server in france are having problems with each other so my ping went from 100 to 400 and i could not find a way to fix it, tried different DNS servers and applications that fix ping etc,
and seems like my only choice is to use a vpn but i recall that i got banned a few years ago for using a vpn, so i wanted to ask what kind of vpns are banned and does anyone have any other way to fix the ping issue
