My web server is (include version): Apache/2.4.57 (Unix)
The operating system my web server runs on is (include version): Arch Linux
My hosting provider, if applicable, is: Contabo
I can login to a root shell on my machine (yes or no, or I don't know): yes
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): no
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): certbot 2.6.0
After using sudo certbot renew all sites are insecure. I use this server for a long time and never i had a problem with renew the certificates. I try certbot certonly and generate new certificates. Restart apache and server failed.
Please follow rg305 instructions but also quit getting more certs. You are almost rate limited if not already. I see 4 certs issued today for that name (you only get 5/week and sometimes the logs are late reporting them)
