This a networking issue, related to firewall settings or IP
address translation.
From the message server 10.40.xx.xxx, the SAP Gateway on
computer 10.40.yy.yyy cannot be reached via port 3300.
Is a
ping 10.40.yy.yyy
on the message server ok? Is port 3300 open in the firewall
settings?
Since "ping" cannot check an indiviual port, you can use "psping"
from

psping 10.40.yy.yyy:3300
I hope that you can narrow down the problem with these tools. Also, it helps
if you can find out which network parameter has recently been changed. In Google
there are a couple of additional hints; search for "connect to sap gateway
failed". |
