Description:
 have windows service (using .net fraemwork 4.5) installed in windows 2012 R2 machine. I have mysql connector 6.9.7 and mysql 5.6.25

When my service is started i am getting following error.

Authentication to host 'xxx.xx.x.xx' for user 'yyyyy' using method 'mysql_native_password' failed with message: Reading from the stream has failed. ---> MySql.Data.MySqlClient.MySqlException (0x80004005): Reading from the stream has failed. ---> System.IO.EndOfStreamException: Attempted to read past the end of the stream.

or some time

Unable to connect to any of the specified MySQL hosts.

If i restart the service in a while all seems to work properly Any idea what's the problem

How to repeat:
Install a windows service which connect ot mysql in windows 2012 r2

more detail i found out is 
What after further investigation we have found that our database version was 5.6.25 . We have tried same connectivity with our old db 5.5.16 and we didn't face the issue. so looks like issue is database itself. our new database is installed in linux machine

Moreover we are just circling in duplicate bugs but neither of the bug has solution.
