Various TLS errors

Post by MartynK » Fri Nov 10, 2017 12:12 am

I am getting various TLS errors reported in the windows System Event Log.

Anyone know anything about them and if I need to worry ?

A fatal alert was generated and sent to the remote endpoint. This may result in termination of the connection. The TLS protocol defined fatal error code is 10. The Windows SChannel error state is 1203.

A fatal alert was received from the remote endpoint. The TLS protocol defined fatal alert code is 42.
