How do I resolve a 502 or 504 error in Internet Explorer?
If error 502 or 504 appears as an error in its own dialog box, that indicates that there is a (usually temporary) Internet gateway error between the computer running the DA client a browser, and the Userful Desktop being administrated. DiscoverAssist versions 0.7.5b and later ignore 502 and 504 errors because virtually nothing can be done through Userful Desktop software to resolve temporary gateway errors (the gateway errors are presumed to be temporary because the browser would not have been able to connect to DiscoverAssist at all if the gateway was persistently down).
