Created attachment 1075473 [details] Bugzilla XMLRPC request data We have a script that watches relevant bugs in Bugzilla. For that it periodically runs specific XMLRPC query against production Bugzilla. It worked till last week when Bugzilla has been upgraded. Now it still works unless 'NEW' is present in input 'bug_status' array. With 'NEW' there it always fails with 502 error code. Please, see reproducer request in attachment. It fails unless you remove 'NEW' from it.
This looks like a proxy timeout. Can you attach your script so that I can see your exact search terms?
