Hello, the pro license (Named User, ArcGIS Enterprise portal) has been moved offline. Then, when trying to return the license to online mode, we get the following message

The procedure for returning a license follows the one described at the link https://support.esri.com/en-us/knowledge-base/problem-unable-to-return-an-offline-arcgis-pro-named-us-000014443
Only instead of ArcGIS Online the local portal is used.
Thanks for suggestions.
