I am trying to change from

0.0.0.0

to

0.0.0.0/project_name

but while running I'm getting

java.nio.channels.UnresolvedAddressException

What's the correct way to change host URL?

You can use

host

method of a

Route

to match requested host and port:

routing {
    host("<http://example.com|example.com>") {
        handle {
            call.respondText { "For <http://example.com|example.com>" }
        }
    }
}

You can find more information here https://github.com/ktorio/ktor/issues/1077.

Thank you
