When attempting to save an appointment as an .ics download, sometimes a “Failed – Server Problem” error message will deny that attempt. There are usually several potential culprits for this situation.

  • Cloudflare Caching
  • Plugins or Site features with Caching enabled

Cloudfare Caching Error

The way Cloudflare’s caching feature works is that it caches static resources to reduce server load and bandwidth. Simply, it is the process of storing copies of files within caches (which are temporary storage locations) so that they are able to be accessed quickly next time.

But, sometimes when attempting to save an appointment as an .ics download (or any other files), this attempt will be blocked by an error message stating “Failed – Server Problem”.

How to Solve

If using Cloudflare’s Caching feature, the best solution for the time being is to temporarily disable Cloudflare’s caching feature so that users can resume downloading their appointments as .ics files to personal calendars.

If any plugins installed have caching enabled, it is best to troubleshoot it by disabling it temporarily.
