After moving my Nextcloud data to a new device my certificate doesn't work anymore

I have a Raspberry Pi 4 with apache2 where I run Nextcloud. I have a certificate for my domain and I use certbot.
I moved my data directory to a new device. After that I can access my Nextcloud files but when I want to see other Nextcloud apps (like calendar), I’m geting an internal server error.
The apache2 error.log says:
localhost:4443:0 server certificate does NOT include an ID which matches the server name
ssl_stapling_init_cert: can’t retrieve issuer certificate!
Unable to configure certificate localhost:4443:0 for stapling

My domain is:

My web server is (include version): Apache/2.4.38 (Raspbian)

The operating system my web server runs on is (include version): Raspbian GNU/Linux 10 (buster)

My hosting provider, if applicable, is: self hosted

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 0.31.0

Hi @GambaJo

it’s not possible to check your domain because the port doesn’t answer.

Checked to see if there is a certificate -

There is no valid certificate.

So OCSP-Stapling can’t work.

Ups, sorry. Wrong domain. Should be

Ok, there is a new certificate (and a new check) -

Issuer not before not after Domain names LE-Duplicate next LE
Let’s Encrypt Authority X3 2020-03-25 2020-06-23, - 2 entries
Let’s Encrypt Authority X3 2020-03-25 2020-06-23 - 1 entries

But the certificate with two domain names isn’t used, so the www version isn’t secure. Ok, not relevant if you use only the non-www version.

The port 4443 is invisible, so it’s unknown if this port is configured.

What says

apachectl -S

Can that port talk with Letsencrypt via port 80?

OCSP - Url:

must work.

apachectl -S

AH00526: Syntax error on line 6 of /etc/apache2/sites-enabled/ncp.conf:
SSLCertificateKeyFile: file '/etc/ssl/private/ssl-cert-snakeoil.key' does not exist or is empty
Action '-S' failed.
The Apache error log may have more information.

Port 4443 is not forwarded but works in my network.

How can I check this?

Disable that not working vHost. Or add there your correct certificate.


should work. But if your Apache doesn’t start because of a missing file, that’s the first problem.

Sorry for the late answer.

Listen 4443

      Require env noauth

But the SSL files exists.


When I do this there is no result, so I think it’s ok.
