The URL in this monitor is based on the httpContext value in the uptime.conf file. You may find that the httpContext value is set to localhost as shown below:

# The context of the up.time HTTP server http://<hostname>:<port>
httpContext=http://localhost:9999

To ensure that the link back URL works correctly, update this field to the proper hostname of the up.time monitoring station.

If this hostname is not resolvable from other networks, some users may not be able to resolve the URL in the email alert.

A restart of the uptime_core or "up.time Data Collector" service is required after applying this change.
