you mean gin -i ....? Using the -i option helped for me

Confirm. In my case gin -i --appPort 8080 --port 3000 run main.go is useful

I ran into this issue as well. Found that if you put the --appPort flag after the run . then it will use the default flag i.e 3001. So as long as I put run . or run main.go at the end of the command everything worked as expected.
