<SAP:Stack>Error while sending by HTTP (error code: 503 , error text: Service Unavailable) (See attachment HTMLError for details)</SAP:Stack>

<SAP:Retry>A</SAP:Retry>

I can see the following contents in attched HTMLERROR file

While trying to retrieve the URL: http://XXXXXXXX/MessagingSystem/receive/AFW/XI

The following error was encountered:

Unable to determine IP address from host name for paymentdev

The dnsserver returned:

Name Error: The domain name does not exist.

This means that:

The cache was not able to resolve the hostname presented in the URL.

Any solution to resove this issue.
