Unable to log in to SEPM server with error:
Checking scm-server log similar error can be found:
java.sql.SQLException: Cannot create PoolableConnectionFactory (Connection reset)
While capture traffic with wireshark there is SSL session setup between SEPM server and SQL but just after that it is Reset by SQL.
This events repeat over and over again.
Examining Server Hello packet coming form SQL server, you can notice that despite client present redlines to set up session with TLS 1.2 SQL server degrades negotiations to TLS 1.0.
SEPM server with external database hosted on other system.
SQL server is not patched to support TLS1.2.
Please install patch that introduce support for TLS 1.2 on SLQ server.
As a temporary solution you can disable encryption on SEPM side (SetSQLServerTLSEncryption.bat) and it will allow you to connect with database and log in - however this communication is not secure.
