In the Proxy Installation Guide it says that I have to create an SSL Certificate because SSL encryption is required for the connections between Client and Server Proxy. In the example shown, a certificate is created which is valid for 365 days.
Questions are now:
Question 1: When the certificate expire, the connection will not be down at all. Agent/Job will not be interrupted.
Question 2: Best practice is to use a valid period, normally it should be 1 or 2 years.
You still can use an expired certificate to use AE proxy but it is not recommended.
