  • SAP Analytics Cloud

Reproducing the Issue

  1. Configure Apache HTTP Server as reverse proxy to create live data connection to on-premium SAP HANA system 
  2. Connect to your SAP Analytics Cloud tenant.
  3. You get the error:  Proxy Error Reason: DNS lookup failure


Instead of hostname, the variable is using SAP Analytics Cloud tenant URL in httpd.conf file for Apache reverse proxy as below:

Define SAP_ANALYTICS_CLOUD https://<customer-prefix>.<data-center>

ProxyPass / https://${SAP_ANALYTICS_CLOUD}/
ProxyPassReverse / https://${SAP_ANALYTICS_CLOUD}/


SAP Analytics Cloud server hostname should be used for the variable SAP_ANALYTICS_CLOUD.

Define SAP_ANALYTICS_CLOUD <customer-prefix>.<data-center>

ProxyPass / https://${SAP_ANALYTICS_CLOUD}/
ProxyPassReverse / https://${SAP_ANALYTICS_CLOUD}/
