I tried to open the arcgis portal page. it's a blank page nothing is shown on the page and i unable to login to the portal admin page . it is always showing unauthorized.
I recently upgraded to ArcGIS Enterprose 10.7 and it was working fine. suddenly stop working. Please help me
I expect that if you go to https://portal.domain.com:7443/arcgis/sharing/rest, the page is returning a 404. The only thing I can suggest is restart the Portal service and see if that fixes it. Is the environment in AWS using content in S3? Unfortunately, these types of problems are tricky to solve and it's best to contact Support Services.
