502 error with cache enabler plugin

[rajasekhar-gundala]

Hello Team,
Thank you very much the product.

I installed the WordPress along with Caddy using docker-compose on Ubuntu server. But got http 502 error when I enabled the "Cache Enabler" plugin. No issue with another cache plugin, WP Super Cache.

I found below logs in Caddy container.
