> We have fallback logic since a long time in the agent to try to connect to the
> server with 2-way SSL if one-way SSL throws an exception. This can cause some
> agents to connect with 2-way SSL (connection timeout exception for one-way
> SSL) and thereby a cluster having a mix of agents, some connected with one-way
> SSL and some connected with 2-way SSL.
> Investigate why we have had this logic and if it is no longer appropriate,
> remove this fallback logic.
