How do I fix a 502 Bad Gateway error in Nginx?
A 502 Bad Gateway error usually indicates that Nginx is unable to communicate with the upstream server. Here are some steps to troubleshoot it.
What are the common causes of a 502 error?
Common causes include the upstream server being down, network issues, or misconfigurations in your Nginx settings.
How can I check if my upstream server is running?
You can check the status of your upstream server by using commands like systemctl status <service> or by accessing it directly via its IP address.
What should I do if the upstream server is down?
If the upstream server is down, you'll need to restart it or investigate the cause of the downtime. Check the server logs for more details.
