Proxy: Catch SSL errors and retry

The SSL library can throw an exception during the XMLRPC method call.  There
is no explicit except statement for this type of exception so they get raised
up and abort the client's processing. This patch catches the exception so that
normal retry processing occurs.

Typical traceback:
Traceback (most recent call last):
