502 on login with nginx
ERROR: 502 bad gateway error
Synopsis: This article describes steps to resolve a 502 Bad Gateway error in nginx by adjusting buffer sizes in nginx.conf and restarting the nginx service.
If you're encountering a 502 Bad Gateway error on Ubuntu and need to adjust nginx settings, follow these steps:
Step 1: Edit nginx.conf:
- Open the nginx main configuration file with a text editor. Add the following in nginx.conf:
:~# nano /etc/nginx/nginx.conf
proxy_buffer_size 128k;
proxy_buffers 4 256k;
proxy_busy_buffers_size 256k;
Step 2: Edit the " \.php$ " section in nginx.conf:
- Locate the \.php$ section within nginx.conf. This section typically handles PHP requests. Add the following configuration directives to the " \.php$ " location block.
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
Step 3: Restart nginx:
- After saving the changes, restart nginx to apply the configuration
:~# systemctl restart nginx
These steps ensure that you've properly adjusted the buffer sizes in nginx.conf and restarted nginx to resolve the 502 Bad Gateway error.
Adjust paths ( /etc/nginx/nginx.conf) according to your actual nginx configuration file location if it differs.
