No route to host
My email has been running smoothly, until 1:30pm EST today.
All of a sudden, no emails are able to send. I disabled the firewall and flushed IP tables, still nothing.
I continue to get No route to host with all emails.
I have almost 1300 emails just sitting in my queue.
Running this
I get
I can ping 173.194.68.27 with no problem.
So my question is, where is this port being blocked and how can I correct this?
telnet ASPMX.L.GOOGLE.com 25
I get
Trying 173.194.68.27...
telnet: connect to address 173.194.68.27: No route to host
Trying 2607:f8b0:400d:c02::1a...
telnet: connect to address 2607:f8b0:400d:c02::1a: Network is unreachable
I can ping 173.194.68.27 with no problem.

Hello :) Are you experiencing the same problem when attempting to connect to other remote hosts besides Google? If so, I recommend consulting with your data center or upstream provider. It sounds like there may be a firewall in place outside of your server causing this problem if the issue persists when you disable iptables. Thank you. 0
