Please Explain This 502 Bad Gateway Error
Peter Carabillo , 01 June 2006 - 02:37 PM Login to Reply 12 replies to this topic Peter Carabillo Members #1 Peter Carabillo 1 posts Posted 01 June 2006 - 02:37 PM I have configured a Windows 2003 Standard Server with CAE 1.0 in single server (access) mode. After installed the SSL certificate, remote clients receive a "Bad Gateway" Error 502 - proxy 502 error The proxy server received an invalid response from an upstream server. Per KB articlehttp://support.citrix.com/article/CTX108577&searchID=20719155 this indicates something in CAE thinks its deployed in a gateway configuration, not a single server configuration. However when I go back to Quick Start, the Access window confirms that I've set it in single server mode.Any help would be greatly appreciated.P.C. 1334-77342-485243 Back to top Kenneth Bell Citrix Employees #2 Kenneth Bell 486 posts Posted 08 June 2006 - 06:49 AM Hi Peter,This could mean that the IIS website isn't starting. If you open the IIS management tool, can you check that both websites are 'started'.Regards,Ken 1334-77342-487702 Back to top Dylan Webb Members #3 Dylan Webb 1 posts Posted 12 July 2006 - 01:33 PM I had the same issues with Svr 2k3 std and CAE 1.5. To resolve the issue i had to uninstall the entire CAE package and do a reinstall -> then configure the external access with the Quick Start menu. Don't use the 'Access Suite Console for Presentation Server' as this seams to confuse the External Access configuration. 1334-77342-499729 Back to top Mark Mair Members

This http://www.checkupdown.com/status/E502.html document references how to fix a common intermittent login issue (Error 502) when Secure Gateway and Web Interface components are installed... SymptomsUsers get intermittent logon issues when trying to reach the Citrix Secure Gateway or Web Interface bad gateway site. The following message is reported:“Bad Gateway! The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST/Citrix/AccessPlatform/auth/login.aspx Reason: Error reading from remote server. If you think this is a server error, please contact the webmaster. Error 502
This server received an invalid response from an upstream server it accessed to fulfil the request. This usually does not mean that the upstream server is down (no response to the gateway/proxy), but rather that the upstream server and the gateway/proxy do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, it often means that one or both machines have been incorrectly or incompletely programmed. Fixing 502 errors - general This problem is due to poor IP communication between back-end computers, possibly including the Web server at the site you are trying to visit. Before analysing this problem, you should clear your browser cache completely. If you are surfing the Web and see this problem for all Web sites you try to visit, then either 1) your ISP has a major equipment failure/overload or 2) there is something wrong with your internal Internet connection e.g. your firewall is not functioning correctly. In the first case, only your ISP can help you. In the second case, you need to fix whatever it is that is preventing you reaching the Internet. If you get this problem for only some of the Web sites you try to visit then it is likely to be a problem at those sites i.e. one of their pieces of equipment is failing/overloaded. Contact the people at those sites. Fixing 502 errors - CheckUpDown Our service monitors your site for HTTP errors like 502. Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to "drill through" to the real computer that actually hosts the Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 502 can easily occur. Please contact us (email preferred) whenever you encounter 502 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software so that they can review the flow of IP data traffic between various computers under their control. 502 errors in the HTTP cycle Any client (e.g. your Web browser or our CheckUpDown robot) goes through the following cycle when it communicates with the Web server: Obtain an IP address from the IP name of the site (the site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs). Open an IP socket connection to that IP address. Write an HTTP data stream through that socket. Receive an HTTP data stream back from the Web server in response. This data stream contain
