PacDisplay Email error -454


#1

Email has been working previously, but now it has stopped and is giving me and error code of -454. I can’t find that in any of the documents. What does it mean?

Using gmail as outgoing server
smtp.gmail.com
port 587, encryption tls


#2

Can’t connect to DNS server.

You can look these up in PAC Control, Help Error lookup.


#3

Just an update for any future visitors:
Our main server was replaced and when that happened the IP for DNS service changed. That really threw a monkey wrench into both Groov and PacDisplay sending emails.

Moral of the story; check your DNS and other IP settings.


#4

Glad you got it fixed.

The better solution would be to use DHCP and prevent the problem in the first place. Problem solved over a couple decades ago.


#5

Except they have Static IPs (for port forwarding) and using DHCP, they likely would have been re-assigned new IPs and I would have lost communication over WAN.


#6

You would set the DHCP server to always assign the same IP. In the IT world, this is pretty much how this is done for anything that acts as a server (Servers, printers, etc.). It keeps your “static IPs” all in one place, you can change/update them in one place, and never end up with a conflict.
