There is a known issue in Uptime IM 7.7.2 where the "HTTP (Web Services)" monitor does not handle redirects properly. The monitor will have a Status of OK and report the Server Response as 302 instead of following the redirect to the next page. This will be addressed in Uptime IM 7.7.3.
In the meantime, a patch is available to resolve this issue. To download and apply the patch, please follow these instructions:
