I have a problem with my server.

I have linux server with centos 6
Don’t have plesk

There ara phpmyadmin and mysql

After install letsEncrypt I can’t empty to phpmyadmin

Este sitio web no puede proporcionar una conexión segura

phpanunzia no ha aceptado el certificado de inicio de sesión o es posible que no se haya proporcionado ninguno.

There is a domain with letsEncrypt certificate, but it don’t have any problem

Could you help me?


Best Regards,



You’ll need to copy the entire http virtual host and convert it to https version.

Thank you


Hi @anunzia

if you have installed a certificate, you must use phpmyadmin with your domain name, not with your ip address.

should work.



Sorry, I Agree
But it’s the same error.

Best Regards,



Could you please share us the https virtual host that controls your phpmyadmin?

Also, please share the output of sudo certbot certificates

Thank you


Ah, now you have shared your domain name.

There is a self signed certificate, not a Letsencrypt certificate.

And there;include_subdomains:false;

is no Letscencrypt certificate created. So I can’t find this domain.

What means this?

Which tool you had used?


Also, some of these errors look like they’re related to client certificate authentication (in which your web browser tries to present a certificate to the server). Is it possible that you obtained a Let’s Encrypt certificate and then mistakenly installed it into your web browser instead of your web server? Let’s Encrypt certificates are meant to be installed on servers.


Thanks you help,

Best reguards,


No /phpMyAdmin necessary. It’s just the domain name.
