When using Russian domains, I get an error

not found in the header Access-Control-Allow-Origin

But this is only associated with IE. Chrome and other browsers work well.

Site test.golovinsky.rf. Project on asp.net core.

  • IE version? And here they write that you need to add domains to the trusted zone. - AK
  • @AK, where is it? :-) - Grundy
  • @Grundy right here on stackoverflow :) - AK
  • Guys, sorry, my fault. I did not say that I use asp.net Core. Cors is configured in the project correctly. All browsers work with a bang, but not from Microsoft. - Cyril
  • What version of IE are you talking about? Try not to use the test. Head.RF , and its PunyCode -> xn - e1aybc.xn - b1abqafeesfb0b.xn - p1ai - Grundy
