Users being blocked - is it load or rate limiting and how to check?
-
We went live with an application at 30 minutes ago, it was fine for the first 15 minutes but now users are receiving an error 429 too many requests.
Does anyone know how we check for this and what config we change to resolve?
Thanks and regards.

Hi @rob-aitken ,
Thanks for using FusionAuth!
If you are seeing a 429 and are using FusionAuth cloud, you are being rate limited by our web application firewall. Our rate limits are not publicly available and may change over time, but are pretty generous. I'd check to make sure you are calling FusionAuth appropriately and/or using exponential backoff when getting a 429.
You can also file a support ticket using the account portal if that's helpful.
