90002 error even while using VPN "WTFast"?

[Lemage]

It used to be just the 90002 error but even though I still disconnect every hour,now I sometimes get the 90003 error instead of 90002.I have not found any info on the 90003 error.Nothing on it on google,game forums or this game's reddit page.

Just what is required for this game to run properly when every other game runs fine?

This game requires a bit more of a stable connection than 2 cans tied by string. I'm willing to bet your disconnections are due to a line stability issue, most people who ask me about their disconnections end up having more packet loss and line jitter than your average copper cabled ADSL connection wired by a monkey on stilts with coke bottle glasses.
