Hello,
we have a problem with live data connection to HANA from Analytics App. On development system it works with basic authentication or certificate. On production system we only see "Loading..." in the iOS analytics app. We couldn't find any difference in configuration settings between both HANA systems. iOS syslog shows:

Problem could be line " CredStore - performQuery - Error copying matching creds. Error=-25300 ". Access to
https://<HANA_SERVER>:<HANA_PORT>/sap/bc/ina/service/v2/GetServerInfo
works on safari browser on the iPhone. Any idea what could be the root cause?
Thanks, Markus
Request clarification before answering.
Hi - do your authentication methods match what is listed in the SAP Help? See https://help.sap.com/doc/00f68c2e08b941f081002fd3691d86a7/release/en-US/5ca20164cc7c4a8d95acd539d98e... - shows some areas where features have "limited support"

Hi Tammy,
we use CORS and no Reverse Proxy for connection. Login method is using an X.509 certificate like described here:
