In the website it is showing this error for almost all APIs
Failed to load resource: the server responded with a status of 502 (Proxy Error)
XMLHttpRequest cannot load. No 'Access-Control-Allow-Origin' header is present on the

HTTP status code 503.
NOTE:CORS has been already installed using npm but still getting the above error.
And sometimes getting this error
Failed to load resource: net::ERR_INCOMPLETE_CHUNKED_ENCODING
When checked log using rhc tail command got below log
