Since installing 9.707-5 we have had several external users who are getting proxy errors (502) and request timeouts when accessing our websites. Doing the same thing locally does not incur the same errors and works fine. This started right after installing the latest patch.
Any ideas on how to troubleshoot? Everything appears to be working just fine and configured correctly, but they continue to have these errors. The back end servers are working just fine so we suspect a communication issue OR a firewall issue.
