We have a self hosted jira instance with IP whitelisting. We want to connect asana with jira but, of course, it’s not getting any connect, as the IPs are not whitelisted, yet.
As Asana seems to be hosted in AWS, we tried reverse lookup of app.asana.com to whitelist, but it fails.
I believe you should keep working with support on this. I know one of my clients (Enterprise plan) is working closely with the support to get this resolved. I am not sure if you’ll get the same level of support but it is worth trying!
