Answer 1

Are you sure supplied credentials are valid for PIISUSER?
1) HTTP response does not contain a valid XML root tag or Error 'HTTP status code 400 Bad Request' while executing HTTP request (calling method 'get_status')
The error 'HTTP response does not contain a valid XML root tag' occurs when path prefix of the destination is '/dir/hmi_cache_refresh_service/ext'.
The error 'Error 'HTTP status code 400 Bad Request' while executing HTTP request (calling method 'get_status')' when path prefix is '/dir/CacheRefresh'.
Solution: Go to transaction sm59 and open destination of type 'H' INTEGRATION_DIRECTORY_HMI. Select "Connection Test". The connection test should return HTTP response 200.
Now go to "Logon & Security" tab and ensure that username and password are stored in the system. Fixing credentials should fix the problem.
Note: Credentials cannot be tested via "Connection Test" tool. If used credentials are wrong, the server simply returns login html page (using HTTP response code 200). As the login html page is not a valid cache refresh xml document, an error is shown in sxi_cache.
