How do I configure my network for Zendesk Chat?

For Chat to have an optimal connection, consider the below.

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.
