cron & max_execution_time

On web hosting accounts, the cron is likely using the default server PHP and default PHP.ini unless you you a path to another version of PHP and a path to a php.ini file.

The default max_execution_time is likely 30 seconds on many servers. This likely is not enough time for resmush.it and can cause time-out exceptions. (It happened to me.)

The cron can be run with -c /path/to/php.ini to overcome this.

This probably should be pointed out on the cron instructions.
