getting the following error when using certbot renew
I would of thought the automatic mode in the installer would add a cron job to autorenew

Yes you are right about the cronjob I’ll add it to the backlog in order to add it to the scripts.
The error you are facing can be workaround using DNS auth instead of webauth in lets encrypt. I think it will lead to less problems if we switch the scripts to DNS auth method by default, will investigate it too.

Yes, sorry @tomtomlincs I haven’t posted any info regarding the let’s encrypt setup. Yeah you need to add a DNS record. Here more information: [https://letsencrypt.org/docs/challenge-types/#dns-01-challenge](https://letsencrypt.org/docs/challenge-types/#dns-01-challenge)
