Appian Community and Appian Academy are being upgraded. As a part of the upgrade, Appian Community is currently in read-only mode, and user registration is disabled until August 3. We apologize for any inconvenience this may cause, but a more secure, stable, and performant Community experience is coming soon!

The new Appian Community launches August 3, followed by Appian Academy on August 7. During the migration, Appian Community Edition, Appian Academy, Documentation, Certifications, Instructor-led Customer Training, Partner Sales Training & Accreditation, and Forum (for Appian Partners and Customers only) will remain available.

Integration not working in Appian but working in POSTMAN (Appian could not find a DNS address)

Certified Senior Developer

While trying to call an API, we are getting an the below error:


success: false

result: null (Null)

error: Integration

Error title: "The external system could not be found"

message: "Appian could not find a DNS address for https://eis-apim.deviq-uat.work.iqvia.com"


The call to this API worked fine in POSTMAN and the connected system with the credentials got authorised successfully as well.

Is there some kind of setting with the network that needs to be changed to allow calling this integration endpoint?
