Sounds like the Pro machine is having a problem connecting to the license manager through the specified ports.  Refer to the following document on how to configure the ArcGIS License Manager with a firewall.  You need to open ports 27000 and a predefined port for the ArcGIS vendor daemon.  Both ports must be open.  If both ports are already open, check the license manager name in the Enterprise portal.  Verify its using a hostname that is recognized by the client machines.  Below is the link to the firewall document to get started:

I do not in this scenario. I would recommend reaching out to technical support on this.

Thanks @George_Thompson for your reply,

I have already configured the License Server Administrator on the Portal for ArcGIS machine, but the error still persists on the ArcGIS Pro machine.

I double-checked with the IT team to ensure that port 27000 is open.

However, the issue remains unresolved. Do you have any further advice?
