I am running a wordpress website on my Apache2 Server behind Proxy. Wordpress "/wp-content/plugins/js_composer/assets/js/dist/js_composer_front.min.js**?ver=5.5.2** " doesn’t load and give me error 522 on chrome browser until I Purge Everything from cashing section on cloudeflare or until I load .js file manually without ver=5.5.2 in the browser.
My Caching Level is Standard Browser Cache Expiration is 30 mins. I am not using any chasing on my Proxy Server.
I wonder if someone can help to solve the problem
