Hi community, I try connect to my Arcgis Pro 3.4 update 3 with an ArcGIS Enterprise 11.4 but when type my user and password show me the next message:

an unknown error has occurred. contact your administrator to check that your licenses are valid

- This Account is a Named User and not required LIcesne Manager because it is ArcGIS Enterprise 11.4

- Checking the license, the user has been assigned a Professional Plus license. 

- It is a LAN connection, open ports for both connection

Tank you for your support

When creating a license file for Enterprise 11.4, it is important to provide the URL portal for that machine.  Check the Enterprise portal log file.  It may display errors pertaining to the Pro Named User licenses.  If this is the case, go back to MyEsri and edit the Enterprise license file you previously created.  Verify you have the correct portal URL and download the updated license file.  Authorize Enterprise 11.4 with the new file.  Review the log file or proceed to start Pro.

Thank you for your feedback, and yes we check the licenses of portal and we created a new license with a custom URL  and we were able to start in ArcGIS Pro.
