Seems LetsEncrypt treat westus.azurecontainer.io as one domain and has a limit on it. One of my new domain got this error:
Error: urn:ietf:params:acme:error:rateLimited :: There were too many requests of a given type :: Error finalizing order :: too many certificates already issued for: westus.azurecontainer.io: see https://letsencrypt.org/docs/rate-limits/
I’m wondering if LetsEncrypt can treat subdomain like
mydomain.westus.azurecontainer.io as one and set rate limit for each one of them.
