txAdmin Port Conflict (Port xxxxx Already in Use)
Why This Happens
txAdmin uses a dedicated web port (commonly 40120) to run its management interface. This port is automatically assigned and managed by our hosting platform.
This error occurs when that port is already in use, most commonly due to:
-
A second txAdmin instance attempting to start on the same server
-
A previously stopped service not releasing the port correctly
-
A manual configuration change that altered port assignments
-
Another internal service temporarily occupying the port
When this happens, txAdmin is unable to start and the server may fail to launch properly.
Important Notice – Do Not Change txAdmin Ports
We do not recommend that customers modify, update, or manually assign txAdmin ports.
txAdmin port mappings are tightly integrated with our infrastructure. Changing them manually can cause:
-
txAdmin becoming unreachable
-
Server startup failures
-
Port conflicts with other services on the node
For this reason, txAdmin ports should only be modified by our support team.
What To Do If You Encounter This Error
If you see a message indicating that port 40120 is already in use:
-
Do not attempt to change any ports
-
Open a support ticket immediately
-
Include the error message from your server console
Our support team will:
-
Identify the port conflict
-
Reassign txAdmin to the correct available port
-
Restart and verify your server is functioning normally
This is a backend configuration issue and will be resolved for you.
