Firewalls can be port dependent. You may not be able to get to port 1880.

If you power off the node red server does ping stop working? That proves that you are talking to the right computer.

**Can't ping when node-red server power is off.**

**when I try "curl 172.16.11.38:1880" from windows desktop, it shows time out.**

```auto
C:\Users>curl 172.16.11.38:1880
curl: (28) Failed to connect to 172.16.11.38 port 1880 after 21036 ms: Timed out

```

**when I try "curl 172.16.11.38:1880" in local, it works.**

```auto
delmar@maxdev2:~$ curl 172.16.11.38:1880

Well that proves the problem is external to the server. Either the router or the windows machine is blocking the port. Or possibly a subtle issue with the firewall on the server, but that is less likely. Do you have any other machines or mobile devices on the network to try?

`nmap 172.16.11.38 -p 1880`

Hi Colin,

Thank you so much for your help. Network guy fixed the issue and it is iptables issue.

Do you mean it was the firewall on the server, blocking that port?

add this to iptable:

```auto
-A IN_public_allow -p tcp -m tcp --dport 1880 -j ACCEPT

```
