I am currently experiencing a problem when attempting to open my e:mail account. I get an error message, stating: "HTTP ERROR 502 - Problem accessing ZCS upstream server. Cannot connect to the ZCS upstream server. Connection is refused. Possible reasons: (1) upstream server is unreachable; (2) upstream server is currently being upgraded; (3) upstream server is down. Please contact your ZCS administrator to fix the problem." I have been getting this message all afternoon and evening. A response can be sent to [email removed for security]. Thank you.
