Problem with Keycloak javascript client

I m running keycloak 12.0.2 and when configuring my javascript frontend with keycloak js adapter everyting works on localhost. But when I deploy to the server it is not working. I increased keycloak logigng level and saw these kind of lines in the log

10:51:55,047 DEBUG [io.undertow.request] (default I/O-2) Matched default handler path /locales/en/translation.json

somehow all requests are going via keycloak, or something?

When running client on localhost, I dont see those. For testing purposes I have Valid Redirect URIs *, Web Origins * and Root URL point to client hostname with https…if I remove that Root URL then localhost stops also working.
