We have an Enterprise deployment where the Portal apps are failing to load. When loading the apps, they're trying to load resources (esri.css, js) from the 7443 internal URL to the Portal. Due to self-signed cert on the 7443 URL, these apps fail to load.
For example opening: https://serverDEV/portal/apps/Minimalist/index.html fails as it tried to load https://serverDEV:7443/arcgis/jsapi/jsapi/esri/themes/calcite/esri/esri.css and https://serverDEV:7443/arcgis/jsapi/jsapi/
The strange thing, in our environment we also have a Test deployment, which has been configured exactly the same and all the apps load properly. That is, these apps load without the 7443 port, thus go through the WA and make use of the proper certs. Ie, the apps properly reference/load: https://serverTEST/arcgis/jsapi/jsapi/esri/themes/calcite/esri/esri.css
I've done a side-by-side compare of URLs and configuration inside the portaladmin. Both these deployments are configured exactly the same.
Any ideas which may account for how/why the apps are trying to load with the internal URL/port?
Before I unregister / re-register the WA, can anyone confirm that this process would update the references inside these apps?
