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
