Description
We had a problem because of a bug where openssl version prior to 1.0.1 were incompatible with version 1.0.2 and up. So when you migrate rudder from 4.X to 5.0, you can have agent <-> server connection failing.
The only solution in that cases are to update agent to a compatible openssl version (ie: use 5.0 agent with embeded ssl) or use relay server built with a specific openssl version compatible with both pre- and post-1.0.1 version.
This need to be documented in upgrade, with a big warning.
