ERR_CONNECTION_TIMED_OUT can ping, but cannot browse

Submitted by onmagic on Sun, 09/13/2020 - 00:03

HI I found that :

for this server , I can ping it, but when browse webmin, it will keep loading and then ERR_CONNECTION_TIMED_OUT

I have tried use another pc under same ip, it is the same

I have tried use another pc, not same ip, then it works

so I want to know why can ping but cannot browse

I have already stopped the firewall and iptables, and not add any security rule inside because it is a new server, why the problem still happen...

How can I know what happen from log

Status: 
Active

I have tried the use nmap to check the connection found :

use the pc cannot connect to test : result is : PORT STATE SERVICE 10000/tcp filtered snet-sensor-mgmt

use the pc can connect : result : PORT STATE SERVICE 10000/tcp open snet-sensor-mgmt

so anything I need to do on server to fix this problem ?

Howdy -- thanks for contacting us!

A good place to start with that is to ensure that Webmin is current active -- to do that, what is the output of this command:

netstat -anlp | grep :10000

If it's not showing as listening on the port, we may just need to restart the service.

it will show it is listening tcp 0 0 0.0.0.0:10000 0.0.0.0:* LISTEN 11029/perl

there are 2 PC, PC A , and PC B, when change the port to 8888, PC A and PC B can access when change back to 10000 PC A cannot access, PC B can access

then I guess is it possible the server provider's problem to block PC A ip to access port 10000, I sure not set anything in the server to block PC A ?

What is the output of this command on your server:

iptables -L -n

That will show what the firewall rules look like.
