I have a test demo. It can reproduce this problem.

package main

import (
	"fmt"
	"net/url"
)

func main() {

	url, err := url.Parse("127.0.0.1:8080")
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(url.Host, url.Port())
}

parse "127.0.0.1:8080": first path segment in URL cannot contain colon
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x28 pc=0x10b025a]

goroutine 1 [running]:
net/url.(*URL).Port(...)
go1.15.3/src/net/url/url.go:1120
main.main()
main.go:14 +0xba
exit status 2

You should provide more message.
