As it has for some time. Make sure your code is up to date, either no cross domain or use proxies; ensure content isn't mixed, etc.&nbsp; You may also want to configure your web adapter as I see it's using the default port number in there. If you use a web adapter you can cut out the port in the URL.</P></BODY></HTML> Wed, 22 Jan 2020 22:33:08 GMT https://community.esri.com/t5/arcgis-online-questions/has-anyone-had-issues-with-a-call-to-their-server/m-p/95059#M4583 Anonymous User 2020-01-22T22:33:08Z
