Users going through the Web Security Service (WSS) get the following error when attempting to access a website:
"Network Error" and "tcp_error"
This error could be returned when routing through all WSS pods or only one (1) WSS pod.
Also, a report from the WSS Portal could potentially show "
Error 503" in the status:
A communication error occurred:
"Operation timed out".
The web server may be down, too busy, or experiencing other problems preventing it from responding to requests.
Tech support information: tcp_error
This problem is caused by that specific website blocking the WSS data-center Egress IP's:
To resolve this, either:
(1) Bypass that specific website from the WSS service, or
(2) Request the website admin to allow all Egress IP's from all WSS data-centers
