Causes: This error is is generated by the Connector when it is either unable to connect to the proxy servers or the connection times-out. There are several possible reasons why users may see this error: The firewall or a error 503 device on your network is blocking port 8080. The firewall is throttling connections to our proxy servers. There is another service running on the connector machine that is trying to use port 8080. Resolution: You can troubleshoot this issue as follows: Telnet to port 8080 of your primary tower and the backup tower from the connector machine.

[closed] up vote 41 down vote favorite 10 we have a asp.net MVC application deployed to a server, and but when there is too many request to the server, the client will just get a "503 service unavailable" error. But if I deployed the application to another server ( lower hardware configuration ), everything worked fine, even more requests it can handle well. My question is what possible configuration can cause the previous server to just throw out a 503 error ? (which means the requests didn't reach our application). asp.net-mvc iis windows-server-2003 http-status-code-503 share|improve this question asked Nov 11 '10 at 2:37 MemoryLeak 3,1211966111 closed as too broad by Flexo♦ Jan 19 '14 at 11:46 There are either too many possible answers, or good answers would be too long for this format.
