SQL Connection String with Encrypt=True

We have been on Winhost for the last year and have been successfully using the following Connection String:

Data Source=tcp:s05.Winhost.com;Initial Catalog=SomeDB;Persist Security Info=True;User ID=SomeUser;Password=SomePassword;Encrypt=True

Today we started receiving DB connection errors. When we remove Encrypt=True from the connection string we can sucessfully connect. Did the SSL certs change on s05??

What is our security risk by not having Encrypt=True present??

 

There is an ongoing issue with the certificate on S05. This should be resolved shortly
