Tested with Squid-4.2 and ended with same results. 
How do we proceed here ?

Translation: Squid did not read enough data from the server to finish
parsing TLS server handshake. Squid needs to read at least 520 more
bytes from FD 15.

And end-of-file on the wrong/different connection.


My recommendations remain the same, but please follow Amos advice and
upgrade to the latest v4 first.

Please note that I do _not_ recommend analyzing ALL,9 logs. On average,
such analysis by non-developers wastes more time than it saves.
