# target mismatch

`TNL_TARGET_MISMATCH`

the framework reported a different listening port from the one tnl dev required.

the registered target does not match the required port

```

## what happened

- the framework ignored or overrode the requested port
- the port was occupied and the framework switched to another one

## if you run tnl

- remove competing port settings from the project script
- when using `--port`, free that port and keep the framework on the exact value
