Portal for ArcGIS: The URL you provided is incorrect

Error Message

When adding an external service URL to Portal for ArcGIS Map Viewer, the following error message is returned:

Error:
The URL you provided is incorrect.

Cause

• An incorrect URL is provided.
• The item service URL is obtained from a deprecated ArcGIS Server version.
• SSL decryption is set up for security purposes. When accessing external service URLs, the security system intercepts the request and replaces the certificate with an internal certificate. Since the certificate is internal, Esri software does not have it in its trust store, making it untrusted.
• The error is returned due to BUG-000158980, which affects ArcGIS Enterprise version 11.1 and earlier.

Solution or Workaround

Provide the correct URL

Provide the correct service URL in the URL box. Refer to Portal for ArcGIS: Add a service or document from a URL for more information.
