Error when connecting to the OGC API server in ArcGIS Pro 3.1. The connection appears to only work after attempting a Web Feature Service (WFS) connection on the service URL first in an ArcGIS Pro session.

Additional Information

Workaround

The connection appears to only work after attempting a WFS connection on the service URL first in an ArcGIS Pro session. This is an odd workaround, but open a project and first attempt to create a new WFS connection with the URL and credentials. After this fails, make a new OGC API connection or refresh an existing connection, and it seems to work.

Steps for the workaround:

1. Open ArcGIS Pro and create new project.
2. In the Catalog pane, right-click the empty space and click New > New Server > New WFS Server.
3. Add the URL to the Server URL box.
4. Add the key to Username and Password. An error occurs.
5. Click Cancel.
6. In the Catalog pane, right-click the empty space and click New > New Server > New OGC API Server.
7. Add the URL to the Server URL box.
8. Add the key to Username and Password.

The connection works, as does adding the layer to the map.
