IDN Domain validation error due to virus_total

I have two domains pointing to the same server (savevader.se and säveväder.se (actually xn--svevder-5wad.se)), the second one contains the "correct" Swedish spelling. They have until recently (~1 month) functioned equally well. The virus total scanner has some time in the past few weeks decided that the IDN domain is potentially malicious. This results in the cloudflare certificate validation failing and the domain not being accessible. I am not sure what I can do to resume the function of that domain?
