Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. [https://crt.sh/?q=example.com](https://crt.sh/?q=example.com)), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help. My domain is: [robotscollective.org](http://robotscollective.org) I ran this command: sudo certbot renew It produced this output: Attempting to renew cert ([robotscollective.org](http://robotscollective.org)) from /etc/letsencrypt/renewal/robotscollective.org.conf produced an unexpected error: urn:ietf:params:acme:error:malformed :: The request message was malformed :: Unable to update challenge :: authorization must be pending.

Hi @scharbonneau > [@scharbonneau](#): > > The request message was malformed :: Unable to update challenge :: authorization must be pending. normally, that error says: Your client is buggy, you send the commands in the wrong order. But that with Certbot? Curious. So I don't really understand your output. > [@scharbonneau](#): > > The version of my client is (e.g. output of `certbot --version` or `certbot-auto --version` if you're using Certbot): certbot 0.31.0 First step: Update your Certbot. ---
