Hello,
I'm starting my adventure with S4H development. Went through WebIDE Personal install guide blog post by Florian Henninger and trying to connect to my S4H system. However I'm getting HTTP Error 500 when clicking on File>Import> Select Application from SAPUI5 ABAP Repository

Here's what I see in the console:

My destination 'S4H' file:
Description=xxxxxxx S4H Type=HTTP TrustAll=true Authentication=NoAuthentication Name=S4H ProxyType=Internet URL=http\://re.moved.net\:44300 WebIDEUsage=dev_abap,odata_abap,ui5_execute_abap WebIDESystem=S4H WebIDEEnabled=true sap-client=100
I made sure the SICF services are active in SAP NW.
I am able to download xml file from SAP NW url: /sap/bc/adt/discovery using Chrome browser. However the WebIDE has a problem with this for some reason.
Using the newest eclipse SAP WebIDE Personal 1.53.9 trial
No further ideas what can be wrong :( Please help.
PS. I managed to capture the traffic from eclipse orion to the SAP Netweaver server. I noticed that no credentials are passed in the request headers:

Is this intended to be so? When I tried downloading /sap/bc/adt I had to specify user and password. Can this be the problem here?
My SICF /sap/bc/adt node is configured like this:
