This issue is fixed in Symantec Endpoint Protection 14.3 RU6.  For information on how to obtain the latest build of Symantec Endpoint Protection, see Download the latest version of Symantec Endpoint Protection

Work around to this issue is as follows:

(For 14.3 RU5 64-bit version Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Symantec Endpoint Protection\SMC---> "proxyList" REG_SZ)

Create above registry value and update it with working proxy at least one or you can add Semicolon ( ; ) separated list as well.
