Email Server Connections Fail When the STARTTLS Protocol is Used and AVG is Installed

Article ID: 715  |  Last updated: 23 Dec, 2014


The following error is returned when testing connections to email servers configured in Surround SCM or TestTrack on Windows:

‘Unable to establish the socket connection to port 995 on host. Please verify the host IP address is correct. Unable to create local socket resource. Connection failed.’

The error occurs when STARTTLS 1.0 is selected as the protocol to send or receive email.


If AVG antivirus software is installed, it is preventing the Surround SCM or TestTrack Server from establishing and encrypting a TCP connection with the email server. AVG only supports unsecured or implicitly secured connections and STARTTLS is explicitly secured.


Use a different protocol to encrypt communication between Surround SCM or TestTrack and the email server.


Disable AVG email scanning for incoming (POP3) or outgoing (SMTP) email on the Surround SCM or TestTrack Server.
