Thanks @9peppe, Yesterday I post a question about sudo certbot renew --dry-run error. I got answer that I should check something blocking the renewal process. I have fortigate firewall and I have only IPS. other than all the required port in and out is okay.
How to or where should I look into inside my ubuntu machine that my renewal will be okay if IU run --dry-run again? I am not sure what is blocking and don’t know where to look.
What should I do so I can correct error that showing below?
File “/usr/lib/python3/dist-packages/certbot/renewal.py”, line 477, in handle_renewal_request
certbot.errors.Error: 1 renew failure(s), 0 parse failure(s)
