Slow server? Ics refresh problems too frequent?
In version 4.0.24 of amr-ical-events-list, the default http timeout in wordpress can be extended for ics fetches. 5 is the wp default.
Note: using a large number may mean that your calendar page will be slow when it is time to refresh the ics files. Consider the cache frequency too.

How to tell if necessary?
If you occasionally see a little exclamation mark on your calendar page – this is an attempt to warn you that a cached version of the ics file is being used and events may be out of date. Hover over it to see the message.
