Our site is not loading pages getting HTTP ERROR 503

All of our sites are returning errors

Internal Server Error - Request ID: 01FXQG5RR79HKZQ03M57X5055F

We have multiple workers that return html pages this all runs fine last hour they are failing with above errors.

If we refresh - the assets will finally load.

Can we get some help?

Hey,

This should not be returned by Cloudflare, do you have an example URL we can take a look at?
