Problem with the plugin – 502 Proxy Error

  • Hello,

    If I install and configure the plugin and want to check in the frontend whether everything is working, I get blank page with a 502 Proxy error: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request Reason: Error reading from remote server.

    If I uninstall the plugin, everything runs normally. What could be the problem – I have the latest version of WP, Woo, I tried several themes….
