how are you trying to serve it?

"scripts": { 
    "dev": "next dev -p 8080",
    "start": "next start -p 8080",
},

you need to change the package.json scripts like this

nope

but why does 6000 work in next js 12

it does?

yea only 13 and up version not working

that port was likely added to [this](https://fetch.spec.whatwg.org/#port-blocking) list when nextjs 13 released

yeah, next 12 may not work now?

never used port 6000, so IDK

Do you have any reasoning for wanting port 6000?

we already had 6000 for next 12 in a project and don't wanted to change it

for 3 portals. we using 6000, 6001, 6002

migrating to 14

it isn't about nextjs ig?

depends on the os

running in docker ubuntu: 20

and os next 12 works and 14 doesn't on 6000

I don't think it's the os

There's nothing we can do: https://fetch.spec.whatwg.org/#port-blocking

6000 port is blocked

yep seeems like need to change

yeah
