I am a software developer. I wrote a C# app that calls out to my email provider’s SMTP port (smtp.gmail.com). 

Only when Webroot is running, the traffic port (587) gets closed immediately with this error:

System.Net.Mail.SmtpException Message=Service not available, closing transmission channel. The server response was: Cannot connect to SMTP server ::ffff:209.85.200.108 (::ffff:209.85.200.108:587), connect error 10060.

This isn’t a problem with the code, or with Google, as it all works perfect when Webroot is NOT running. It’s only when I QUIT (shutdown) Webroot entirely, does it actually then work just fine. 

I’ve even disabled all the individual Webroot components (real time shield, web shield, firewall) - that didn’t help. I uninstalled and reinstalled Webroot - that didn’t help.  I added my application (.exe) to the file and script exceptions settings - that didn’t help. I don’t see a way in Webroot SecureAnywhere CE to add firewall exceptions. 

Hello ​@kennedystephen 

It would be best to contact Webroot Support to solve this problem.
