I am trying to import a Custom Widget into Portal for ArcGIS. I have version 10.6.x. On my local machine I put the unzipped widget into my www root folder. Following the instruction I get the following error message: Unable to load https://<gis.domain.com>/portal/sharing/proxy?https://<DESKTOP>/esearch/manifest.json status: 400. I am not sure how to proceed..
Any suggestions?
I think I resolved this issue. For the benefit of others, put the custom widget in the www root folder opn the webadaptor machine. Sync right up!
