Automation Service — Shortcuts fail or time out

I have several shortcuts running through Pushcut. Most work fine. But I have a few that turn lights on/off, set the thermostat and activate our alarm that are marked “failed” or “timed out” in “Monitor Requests.” If I set the same shortcuts up as scheduled in Pushcut, they work fine. Am I doing something wrong? I just started using Pushcut a few days ago. Thanks in advance for any help.
