Localhost11501 | Portable
If you find another process using the port, you have three options: change your portable server's port to another number, stop the conflicting service (if it's not needed), or close the other application.
While a portable environment runs locally on your loopback adapter, you may occasionally need to show your work to a remote client or team member. Instead of migrating your project to an expensive cloud provider, use free reverse-tunneling tools directly from your portable device: localhost11501 portable
