Something strange happened today, which looks like a little update to HCP. A small icon to check connection looks a bit different and once clicked the "hourglass" seems different too. These are cosmetic changes only but the error message today (without any changes made by me) is as follows:
Strangely, despite the error message HTTP connection from HCP to my backend system through Cloud Connector seems to be working fine. I still don't understand why connection check fails. I very much hope SAP will add some troubleshooting guide to Cloud Connector setup document. If SAP really want HCP to be used by more customers the critical part like the Cloud Connector must work flawlessly and now it seems VERY random.
