Hey. I am a Software Engineer and I am building a web app for our guild that just lists all members and check their online status in game. It uses Flutter 2.2 web but I am receiving a CORS error on my GET request with this URI https://armory.warmane.com/api/guild...ecrown/summary but for my Android (APK) and Windows builds are fine and can fetch data from Warmane servers.
Looking forward to speaking to a developer who can help me out with this.
You can't make XHR requests to other domains unless you are whitelisted, you will get a CORS error. The easiest solution is to proxify the requests through your own domain.
