Thanks for reaching out! I hope you're having a great day so far—happy to lend a hand here.
I reviewed the Zap history and it seems like we've seen multiple instances of the Zap trigger recently. I have attached a screenshot below.
For the errored runs, Unfortunately, this is due to a limitation on the Instagram side, I’ve checked here and they have a limit for 25 posts via API per 24-hour window.
This limit is probably also divided into smaller timeframes as well so that’s why sometimes it will fail if you try to post to Instagram via the API in rapid succession.
Since it looks like this is a time-based limitation in their API, one option here would be to replay the tasks later and they should then work. You can read more about replaying tasks here: https://zapier.com/help/manage/history/replay-failed-zap-runs
Another more complicated, but slicker solution would be to avoid this by spreading out the automated actions using Delay by Zapier:

The helpful option here would be Delay After Queue. This is a method that can be used so that all of your actions are forced to “take turns”. Each action that is put into the queue will wait for the amount of time set in the Delay action after the previous action took its turn before taking its turn. So a delay of 60 minutes for example would ensure you never exceed the 25 posts in 24 hours limit (also for example if the 25 is broken down into hours there might be an hour limit of 1 post per hour which likewise delay would avoid)

Please let me know if that helps you, and if you have any further questions feel free to reach out. I’ll be glad to assist you.
