I’ve been trying to connect to SAG Repository from CCE 10.3 Fix 6.
The error in default log is
WARN #58 Error: (id: [1552951045201]) Cannot connect to Software AG repository: Connection timed out (Connection timed out) caused by: javax.ws.rs.WebApplicationException: Cannot connect to Software AG repository: Connection timed out (Connection timed out)
Looks like the account which you are trying to use is missing permission to download from SDC.
try with the user who have a download permission in SDC(Software AG repository)
Wolfgang your link is referring to docker configuration. I am not using docker container at this time. My installation is on Red Hat v 7.x only and am trying to configure CCE proxy from console GUI.
