[maxime-aubry]

I Have a NestJS project.

Even if i change port number, i always get this error.

if you're using Bun.serve then you have to specify the hostname next to the port number to set the port

I also see this error on windows for a few days now.
Removing port from serve or setting a hostname does not change anything.

I havent set port to 57151 (or 0)!

seams windows related as it works on linux or inside WSL

@BennyAlex I believe your issue is #15425 and should also be fixed in canary:

bun upgrade --canary
