Today I updated PHP SDK from 2.1.2 to 3.0.1 and still get these errors. Usually the most common is the connection timeout SLL, eventually you conect () timed out!
Curiously, I was just another exception, this happened only once:
Exeption grabbed: SSL error: reading of 00000000: lib: (0): func (0): reason (0), errno 111
Anyone else experience this too?
