Error: Let's Encrypt validation status 400
Today I upgraded Debian 12.1 to 12.2 and installed MyVestaCP control panel on my VPS. I am trying to install the Let's Encrypt certificate for my domains, but it is giving an "Error: Let's Encrypt validation status 400" error.
I searched online for its fix, but none of those fixes worked for me. Any help or suggestion to fix it will be great.

Check your DNS and A record s
Any log?
Ditch MyVestaCP. It is run by single person. HestiaCP is more predictable and more supported (their forums rocks!).
It's correctly set.
I will check it. Thanks
It seems that the problem was with Debian 12.2. I installed Debian 11.8 and LetsEncrypt worked without any error.
The error you're seeing is likely from Let's Encrypt's validation failing. A common cause could be misconfigured DNS or a firewall blocking access. Check your domain's DNS settings and ensure your VPS firewall allows HTTP/HTTPS traffic. If those are set right, look into MyVestaCP's logs or reach out to their community for more specific help.
Yeah? You didn't read the comments above. The issue in this post has already been resolved.
