Environment
- Qlik Data Gateway - Direct Access (All versions)
Resolution
It is suggested to make sure that both their tenant hostname (for example a12345bcdefghijklm.us.qlikcloud.com) and the tenant alias hostname (for example mytenantqlik.us.qlikcloud.com) are allowlisted on the machine hosting Data Gateway and that HTTPS (port 443) and WSS traffic are not being blocked.
If this configuration has been verified and things are still failing, don't hesitate to contact Qlik Support.
Cause
Traffic being blocked leading to intermittent failures.
