I am trying to install ArcGIS Server 10.5 on a server with Windows 2012. The installation runs through, as does the software authorization. When I head to http://localhost:6080/arcgis/manager and create a new site, I receive the following error message:
‘Failed to create site. The machine does not have a valid license. Please authorise using the Software Authorisation wizard for ArcGIS Server’
After reading previous discussions on this topic, I checked the keygen files and the licenses should be valid for the coming months. Also, I opened up all the ports mentioned in the ESRI helpfile. Finally, I tried to use 127.0.0.1 instead of localhost, to no avail.
Would anybody here have an idea. Thanks in advance.
