502 Bad Gateway and Nginx

[bliscar]

Hello,

 

Since I have migrated my website under prestashop to a VPS using Nginx, i always got the same error (502 bad gateway / Nginx) when i try to authenticate on the front-office.

 

Did anybody experience the same problem ?

 

Thank you in advance.

this is going to be a bit technical, but you likely need to reconfigure your nginx settings to support a higher proxy buffer settings.

 

you could start here

proxy_buffer_size 128k;

proxy_buffers 4 256k;

proxy_busy_buffers_size 256k;
