[keycloak-user] Host header verification during introspect?

As i wrote a couple of days ago, i have an issue with introspection. When sending an introspect request through proxy i get a pretty uninformative {"active" : "false"} as a result. I have two proxies, private and public and all the requests to keycloak go through them. When i get a token from private proxy (http://private .com/../protocol/openid-connect/token) and then try to access introspect through public proxy (http://public/../ protocol/openid-connect/token/introspect) with this token, it fails with an error i provided above. Token is issued to private proxy, obviously. When i receive a token and use it to access introspect through the same proxy, it works. I've tried to modify my proxies to hack Host header and replace it with whatever the token is issued to and it works when i manually do the steps above with postman, but unfortunately it horribly breaks something else within my code. I get that it's more secure this way, but i did not have this issue when i used 1.9.8.Final. Is there a way to disable this introspect host checking with the 3.0.0.?
