prometheus can not bind ip v4 address

[pc10201]

What did you do?

./prometheus -web.listen-address "0.0.0.0:9091"
./prometheus -web.listen-address ":9091"

What did you expect to see?

I want bind 0.0.0.0 let everyone can see the web.

What did you see instead? Under which circumstances?

 ss -lntup

The ss output doesn't indicate that Prometheus is not listening on v4, even if it just shows a v6 entry. When I run Prometheus in the same way, I get the same ss output, but I can still reach Prometheus on the v4 address. Does that not work for you?

I am sorry.It is OK now.
Because centos firewalld service is active.So I stop it.
