Configuring your network for Chat

For Chat to have an optimal connection, consider the following:

• Traffic from *.zopim.com and *.zopim.io is on the allowed domains list on the firewall. (* is a wildcard and means all subdomains on the zopim.com and zopim.io domain).
• Chat only uses ports 80 and 443, which should be open on all firewalls and VPNs as they are standard ports.
• Chat relies on Amazon for services. If you are blocking Amazon IPs, it could negatively impact Chat performance.
• Ensure this article has been adhered to in terms of allowed IPs: Configuring your firewall for use with Zendesk.
• Ensure you are not blocking any relevant IPs. For more information, see the article: Using IP Access Restriction to limit access to the Chat dashboard.
