LetsEncrypt Errors our and then Says fine

Renewing SSl cert for https://insertdomain.com [Errno 99] Cannot assign requested address ~$ sudo ee site update insertdomain.com --letsencrypt=renew More than 30 days left for certificate Expiry. Not renewing now.

So I got the above error, and then when I retried it says it is fine. I check in the browser and the LE cert is still set to expire at the end of the month.

any known issue with this? I have restarted nginx, and have tested in private mode browsers to be sure there is no cache.
