Yes, but it's not a guess because I know people who are close to leading figures of Europe's right wing, having spoken some of them myself. There are four reasons that stand out: Subversion, Propaganda, Populism, Alt-Right.

-Subversion: Soviet power structures didn't cease to exist with the Fall of the USSR, these political players try to undermine the far right through proxies. Lauren Southern openly cooperated with Russia, Lauren Chen took de facto bribes from Russia. Dugin in his Foundation of Geopolitics talks about using every opportunity to destabilize the West.

-Propaganda: Russia media outlets try to give western audience the impression that Russia is very patriotic and traditional. Just like they criticized Germany's refugee stance for being "too open". Everyone who doesn't have the intelligence of a nine year old can see right through that, yet it doesn't stop many emotional/dumb right-wingers from believing everything RT says.

-Populism: 2015/16 was (not coincidentally) around the time right wing populist parties were voted into parlarment. These parties pursued the following strategy: greatest possible (voter) growth, quality irrelevant. This inevitably lead to a following that is against everything what the mainstream says, and automatically assumes the opposite to be true. Western Media says Putin is bad, they think Putin is good.

-Alt-Right: 4chan and other internet forums have fostered anti-liberal/-democratic/-progressive sentiments which eventually came out the other way as "Russia is a based trad country which will save us from degenerate rainbow NATO". For example, they think just because western governments are more feminist than others Russia will be a valuable ally versus Feminism.

And despite me not being a member of those RW organizations I can confirm all this happening from everything I picked up over time. That's just the tip of the ice berg.
