A gateway timeout error typically occurs when the Web Application Firewall (WAF) takes longer than expected to connect to the backend server. This can happen, for instance, if a user is downloading a large file, which may result in a longer connection time to the site.

Follow these steps to change the protocol:

1. Log in to the Prophaze Dashboard.
2. Navigate to the Settings tab.
3. Click the edit icon next to the domain name for which you want to make changes.
4. Increase the below timeouts value.
