Port issue on render

I am not able to deploy my backend .Its showing error.
This is my code :- const port = process.env.PORT || 80;
console.log(Server is running on port number ${port});


Port 80 is reserved on free instance types, as noted in the docs

A default PORT env var is set to 10000, which the code you shared should pick up, so I suspect you’ve also manually set a PORT env var to 80. You could either delete your PORT env var or set it to a non-reserved value.
