I am now working on a Java web project. It works well in local host using eclipse and Tomcat. But when I deploy the war file to remote server (which is also tomcat), one function at front end return 502 proxy error.
The function requests the server that I deployed and the server will further request another remote server. The whole process will take around 2 minutes. I also check the deployment log. It seems that the server is working well except for returning to front end.
Does anyone have similar problem before?
