Introduction

It reports that it's "not possible to establish a connection with the concurrent license server" and specifies that "The License server (localhost:27000) does not support this version of InstallAnywhere."

Troubleshooting Steps

Step 1 : Check lmadmin log:

root Version: 11.19.0.0 build 284536
root.LicenseEngine started without redundancy.
root.Vendor (mvsn) stopped.
root.LicenseEngine (mvsn) exited with status 27. (No features to serve)
root.Vendor (mvsn) stopped.
root.LicenseEngine (mvsn) exited with status 27. (No features to serve)

and mvsn log,
22:57:03 (mvsn) (@mvsn-SLOG@) === Host Info ===
22:57:03 (mvsn) (@mvsn-SLOG@) Host used in license file: ap-testintool12
22:57:03 (mvsn) (@mvsn-SLOG@) HostID node-locked in license file: 00155dddec04

Step 2 : Verify that the localhost/hostname/ethernet address you utilized for the connection is accurate with the license file.There isn't a feature available to deliver an error message indicating an incorrect host ID or a mismatch with the license file.

Outcome

In the scenario described, utilize "ap-testintool12" to establish a connection with the concurrent license server, ensuring that the host entry in the license file matches. If the host ID matches, the connection will be successful.
