If you're getting a weird 502 Bad Gateway error with Laravel Valet and, most probably Drupal, chances are your Nginx error log is screaming:
upstream sent too big header while reading response header from upstream.
This is because such resource hogs as Drupal send too big payloads when running in development (or any? ;) mode, and as a result, Nginx fails.
But we can fix that. And no, you don't have to throw Drupal away (most probably you should, but finish the project for the client first).
1) Go to
~/.config/valet/Nginx directory and create or edit
2) Add the following contents to it:
proxy_buffer_size 128k; proxy_buffers 4 256k; proxy_busy_buffers_size 256k; fastcgi_buffers 16 16k; fastcgi_buffer_size 32k; fastcgi_busy_buffers_size 32k;
3) Save the
4) Restart valet:
And you should be good again! Ha-ha Drupal, eat that, you won't ruin my day this time!
