Unable to sign into licensing portal after upgrading to ArcGIS Enterprise 11.5

[aorton_blueraster]

For ArcGIS Pro licensing, we use named user licensing with ArcGIS Enterprise. This worked fine at 11.2 with ArcGIS License Manager 2024.0. We did an in-place upgrade to ArcGIS Enterprise 11.5, and now all ArcGIS Pro users get either of the two following error messages when launching ArcGIS Pro:

"The assigned license was not found. Please contact your administrator for more information." or "An unknown error has occurred.  Contact your administrator to check that the license manager is running with valid licenses."

We have tried:

• Uninstalling ArcGIS License Manager 2024.0 and rebooting the Portal for ArcGIS machine
• Clean uninstall/reinstall of ArcGIS Pro
• Tested both built-in and SAML users, as well as a new user
• Tried different license files with and without "https://" at the beginning of the portal URL
• Confirmed registry key-values on ArcGIS Pro client

Are there any other suggestions to get ArcGIS Pro licensing to work?

We had a similar issue when we went from 11.3 to 11.5. Pro opened up fine for some users and wouldn't for others - citing a licensing issue. I had my IT administrator recycle the License Manager (similar to what we use to have to do when we had ArcMap and concurrent licensing). I also had my editor verify they were accessing Pro using the Named User and Enterprise Portal. Turns out that somehow in all that, this particular editor's copy of Pro had reset the license back to Concurrent Use. I'm not sure which option fixed the issue, but it's worked fine ever since.

With the help of Esri Support (thanks Wasan!), we resolved the issue by cancelling the license file and creating a new one. It didn't appear to be corrupted when looking at it in Notepad, but there must have been some issue with it. All is well now!

I'm having this exact issue with 2 of my portal deployments. The licenses page shows pro licenses, yet no one can access them. Hopefully esri fixes this bug sooner rather than later.

Did you try cancelling and re-generating the license files (not just editing an existing license file)? Also, @TimoT mentioned making sure there's no trailing slash in the portal URL. Not sure if that makes a difference or not.

Hi @aorton_blueraster 

Starting at ArcGIS Enterprise 11.4, License Manager is no longer required to enable named user licensing for ArcGIS Pro.

When generating the license file with Pro add-on extensions in MyEsri, you'll be prompted for your Portal URL. In our case, we had to ensure there was no trailing slash in the URL. Haven't tested this extensively, but it's possible that it just needs to match your Portal's webcontext URL.

After you have imported your updated Portal license file, you can assign Pro licenses via the Portal UI as documented:

Thanks for the suggestion. We didn't have a trailing slash, and kept everything just the same. It seems like re-generating the license file did the trick.
