How to fix this error?

Read the following error messages to find out more about the
communication error.
In general, check in transaction SM59 that <LS>Host</> and <LS>Port</>
are maintained correctly for destination XSA_ADMI (default name of
destination to XSA controller). In addition, check that the connection
test for this destination returns no errors.
For more information about this destination, see the section
<LS>Creating Destinations in ABAP</> in the configuration guide
<LS>Configure your ABAP Development System for Development of HDI
Objects</>. The guide is linked in SAP Note 2569651
(https://launchpad.support.sap.com/#/notes/2569651).
If you do not use XSA_ADMI as the default name for the destination to
the XSA controller, you find the name of the destination used in the
system using transaction <LS>SCTS_HTA_TOOLS -> Define Parameters of
HTA-for-HDI Configuration</>. The value of the <LS>Destination for XSA
controller</> parameter is the name of the destination that HTA uses to
connect to XSA controller.
Note: If transaction SCTS_HTA_TOOLS does not exist in your system, you
can use transaction SA38 to execute program SCTS_HTA_CONFIGURATION to
find out the name used for the destination to XSA controller.
If this doesn?t solve the issue, check the troubleshooting sections in
the configuration guide or in SAP Note 2569651 for further information
about how to proceed when errors occur.
