What can I do to prevent API services from being rejected by the server?

Until recently the datastore I had been using was giving me no issues. It wasn't until recently that every once in a while it would throw this error

I've dug around but I haven't found anything on what this is or how I could fix it.

This is a web error. There is nothing you can do to fix it.However, you can prevent if from halting your script. Putting api requests like datastore in a pcall() will stop it from yielding. pcall() is kind of like a fail-safe. If anything goes wrong inside it, it will stop executing the code, and carry on executing the next part of the script.
