I think these should be useful, although it’s not always easy to know from the report themselves the real nature of the issue/problem.
For the SSLHandshakeException, I think it’s likely that this will be due to the user having their device date set to something where the server doesn’t recognise the certificate as being valid. I know this can be an issue in Ethiopia, where I’ve seen people set the phone date to an approximation of the Ethiopian calendar, so then the server SSL certificate is not recognised by the phone as being valid.
I’ve also seen the UnknownHostException message a few times before (though only a handful of times in the last years), and it’s unclear to me the exact reason for this. It might be if the user has a very slow connection, the connection times out before it reaches the server.
I guess the main issue will be on how many times these messages are coming through, how many of these crash/error reports are you getting?
