Layer not displayed in chrome

 

ArcGIS Enterprise 10.7.1 

Browser: only in Chrome

Chrome version:  Version 76.0.3809.100 (Official Build) (64-bit)

 

When viewing maps from the <portal> a rest/services json call to the <web adaptor> is blocked 

 

https://<portal>:7443/arcgis/home/webmap/viewer.html?useExisting=1&layers=<id>

 

Chrome devtools console displays the following error:

Cross-Origin Read Blocking (CORB) blocked cross-origin response https://<web adaptor>/arcgis/rest/services/<map>/MapServer/export?<params> with MIME type application/json

 

Because this request is blocked I don't easily see what the response header are.

 

I can see other rest calls returning data that include the following response headers:

 

https://<web adaptor>/arcgis/rest/services/<map>/MapServer?f=json

X-Content-Type-Options: nosniff, nosniff
Content-Type:  application/json;charset=UTF-8
