Missing or invalid credentials for data source. Reason = 'CredentialMissing'

[Anonymous]

Hi All,

I have setup a new on-premise data gateway and followed MS Guide

to configure proxy to connect to teh outside world. It seems everything is workign as expected with regards to connectivity.

Proxy configuration : Proxy settings match for all Gateway process configurations.

Overall Results : 48/48 tests succeeded.

Conneciton to Share Point Online as a standalone works fine too. However in combinaiton with HANA when I am trying to do Get Data from Web it is giving me below error even though the crendetials are correct - It asks me to sign and after signing it it again goes back to teh prompt and finaly it fails . My Data gateway is running with DOmian Account only. ANy idea?
