Webhook call to non-www domain

[AnkitaV]

Hi

I am configuring a webhook with method type as POST for the below URL's

production: https://www.example.com  

UAT: https://www-uat.example.com  

For the prod URL, it is working fine in webhook as well as through POSTMAN

but for the UAT url, it is working fine in POSTMAN but throwing error string as "www-uat.example.com Name or service not known" and no status code

Has anyone encountered this kind of issue before? Any suggestions here please to get this resolved?

Thanks.

Hello @AnkitaV ,

Do you have actual URLs we can look at?

The UAT just looks like a different type of setup for a CNAME.

If you're behind a corporate firewall (including a VPN) when using Postman, the UAT hostname (www-uat.example.com) may only resolve when using your company's private DNS server, but not when using the public DNS infrastructure used by everybody else.

If the hostname isn't public, the UAT webserver may still be available publicly. If it's available publicly, you'll be able to connect to it using its IP address and a manual Host: header in Marketo.

Other than that, you should look at the Postman HTTP headers to see if you have some authorization headers that you forgot about.

Hi Sanford,

The HTTP Headers were correct, the issue was around VPN.

Thanks for helping out.
