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. crt.sh | 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: a1astudios.tk
I ran this command: certbot renew
It produced this output: all renewal attempts failed.
Error 526 Ray ID: 669f46246be0170c • 2021-07-05 08:37:54 UTC
My web server is (include version): ubuntu 18.054.5 LTS
The operating system my web server runs on is (include version): GNU/Linux 4.15.0-135-generic x86_64
My hosting provider, if applicable, is: Vultr
I can login to a root shell on my machine (yes or no, or I don't know): yes login ok
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): bash
The version of my client is (e.g. output of
certbot --version or
certbot-auto --version if you're using Certbot): 1.15.0
To fix this, you will want to:
- (Temporarily) set your Cloudflare SSL mode to "Flexible". See this article.
- Post the full error message from Certbot.

Try set Cloudflare back to "Full".

Thank you _az The site is back and everything looks normal. in the future, I should run the Certbot renew 30 days before expiration? sorry for the stupid question but I'm new to bash and Cloudflare.
Thank you for helping me to resolve this issue that is so vital for websites and people I trained with vultr and Nginx
Ordinarily, your Certbot installation will have come with a scheduled task to perform renewal. It usually runs twice a day, renewing all certificate which are less than 30 days from expiry.
To make sure that you have one, you can try follow the instructions here.
Generally, you shouldn't have to run Certbot to renew your certificates. It should just happen automatically.
To make 100% sure, does a test renewal succeed?
sudo certbot renew --dry-run
