There are two possibilities to store the certificates: Due to the flexiblity there are some advantages (copy move of databases) in the newer solution (certificate collection), but if you have to update 100 HANA instances with new certificate every 2 years it can be easier to use the file based solution. (1) site1 is broken and needs repair; connect string to skip hostname validation: As always you can create an own certificate for the client and copy it to sapcli.pse instead of using the server sapsrv.pse. +1-800-872-1727.
