I am using certbot for my certificates with a varnish cache running on port 80 and apache running on port 81(Docker is using 8080). If i manually make a certificate for *.domain.com and add the acme challenge TXT to my DNS it works fine. However, I went to do a dry run before adding a cron to my system and i got 503 error which is something to do with Varnish and it not being able to reach apache. Is there a way around this so it auto renews without fail? And is there a way for me to have the Cloudflare proxy on and renew without failure? And what command would I use on crontab for automatic renewal of all certs?
