Hi

i,m using Arcgisjava script on my local network and my server has not access to internet. when i load my website, I have this error in console:

Access to fetch at 'https://www.arcgis.com/sharing/rest/portals/self?f=json&culture=en ' from origin 'https://Localnetwork.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Access through with esri resource proxy from your javascript.

Best Regards,
