## what happened

- the target port is missing or outside the valid range
- the target contains a path, query, fragment, credentials, or whitespace
- the target uses HTTPS or a host other than `localhost`, a `127.x.x.x` address, or `::1`

## if you run tnl

- use a bare port such as `3000`, `localhost:3000`, or an HTTP loopback origin
- run the command again with the corrected target
