those messages are not causes of network interference on the game. there's another underlying problem that causes the stop of the loading bar.

thought the message "Scripts may close only the windows that were opened by it." means KC3 was unable to close the window (it was supposed to if you're visiting DMM and getting a new API link. it should close DMM and open the game extension). this was because you opened DMM yourself instead of clicking "get a new api link" from KC3 menu. but on all that, it's harmless.
