ERROR: You have exceeded your Free organization's monthly assigned rate limit for this request

Hello,

I am getting this error:
ERROR: You have exceeded your Free organization’s monthly assigned rate limit for this request

I’ve not come across this before. I’ve only created 13 builds in the last month which seems like a very low rate limit.

Please advise. I’d love to continue using convox at my startup and eventually start a paid subscription once we begin to scale.
