However the farm is set up with hostnamed site collections, and we have a site called https://intranett.otherdomain.anotherthing.com. When adding the webpart to this site. I see CORS errors in the console, and message in the webpart about certificate.
So I am pretty sure this is Chrome and CORS policy. However since I am not really a developer, just like thinkering with stuff. I am not sure how to buypass this. I have found a lot of articles, but I am not sure how to implement them like step by step (for dev dummies).
If someone could give me some advice I would be grateful.
