Subdomain Nginx Timeout During Connect Likely Firewall Problem
What Is a Subdomain in Nginx?
A subdomain in Nginx is a domain that exists under a primary domain that typically has its own content and sits under a directory structure to illustrate this hierarchy. Nginx subdomains are used for various reasons including to target a specific audience, to differentiate content from a main domain, or as an alternative to hosting multiple domains. They are not sub domains in terms of the DNS structure, such as with A records like normally used with sub domains and domains, but are handled by Nginx instead with the use of server blocks.
What Is an Nginx Timeout During Connect?
An Nginx timeout during connect is an event that occurs if the server receives a request, but is unable to respond to it. The most common cause of Nginx timeout during connect is a firewall issue, though there are other less common causes depending on your particular server setup. Nginx will typically display an error message such as “504 Gateway Time-out” when a timeout occurs. This error can be both confusing and difficult to debug, and the resolution is usually related to firewall configurations.
What Is the Firewall Problem?
The firewall problem relates to the way that Nginx handles requests for a subdomain that is hosted externally. For example, if you have created a subdomain called “test.example.com” that is served from an external server, then Nginx will not be able to route traffic directly to that subdomain. Instead, it will send the request to the server that is hosting the main domain, which is where the firewall problem occurs.
The firewall problem is caused by the fact that when the request is sent to the main domain’s server, the server’s firewall is likely to block the request because it does not recognize the external server’s IP address as belonging to the main domain. This results in a timeout during the connection process and can result in an Nginx timeout during connect error.
How to Resolve Firewall Problem in the Nginx Configuration File
To resolve the firewall problem in the Nginx configuration file, you will need to add an additional location block for the subdomain that contains the IP address of the external server. This will tell Nginx that the request should be routed to the external server when it is received and will allow the request to bypass the main domain’s firewall so that the connection can be established.
The configuration block will look something like this:
location / {
proxy_pass http://1.2.3.4;
}
Where the IP address 1.2.3.4 should be replaced with the actual IP address of the external server.
Conclusion
An Nginx timeout during connect is often caused by a firewall problem related to the way requests are routed for subdomains hosted externally. To resolve this issue, you will need to add an additional location block to the Nginx configuration file that contains the IP address of the external server.
