Error certification on virtualmin/Nginx

[DownPW]

Hello mark

It’s strange this evening I no longer had SSL access to my dev environment

I had a zeroSSL CA certificate that was still valid until the end of the month.
I rebooted the machine as well.

So I checked my DNS, Cloudflare, domain name, nginx service, all is OK.
I regenerated a certificate on zero SSL but I got an error saying there is a problem with the certificate (invalid certificate)

Your connection is not private
Malicious individuals may be trying to steal your personal information from the nodebbdev.xxxxxx.fr site (passwords, messages or credit card numbers, for example). Learn more
NET::ERR_CERT_COMMON_NAME_INVALID

I can Bypass the message but that’s not the goal

@DownPW yes, it’s a bit hit and miss, but certbot will work. Have a look at this

It is impossible to verify on the server that it is indeed the domain nodebbdev.test.fr, because its security certificate comes from the domain test.fr. This could be due to a misconfiguration or your connection being intercepted by a hacker.

@phenomlab

Seems to be a configuration problem but don’t know where and why ?
I have installed the ZeroSSL CA certificate on domain and nodebbdev subdomain.

[phenomlab]

@DownPW it looks to me that the cert you are using isn’t a wildcard or for the subdomain.

[DownPW]

d**n, maybe you are right because I’m on a ZeroSSL free account
But I can normally generate a certificate for all subdomains. I didn’t get this message before.

[phenomlab]

@DownPW how are you generating the certificate?

[DownPW]

like this

replace test.fr with my domaine of course. (not subdomain)

[phenomlab]

@DownPW yes, you need a wildcard cert for the subdomain to work. Can you use LetsEncrypt?

[DownPW]

Maybe better, I don’t know how anymore in Virtualmin, there was a bug with virtualmin/Let’s encrypt, I have to look for it

[phenomlab]

@DownPW yes, it’s a bit hit and miss, but certbot will work. Have a look at this

[DownPW]

I did like that from memory and select subdomain but I would like to take a longer time. Memorizing the certificate didn’t last long

sudo certbot --nginx -v

[phenomlab]

@DownPW should be 90 days?

[DownPW]

Yes I guess but it’s not much but it doesn’t matter. I don’t see any commands in the help
Should I delete the Zerro SSL certificate via Webmin before? Think yes

and this bug that we can’t regenerate a certificate without error via virtualmin is really annoying.

Yes.

What is the error message?

[DownPW]

I have regenerate with certbot, reload nginx without errors but it is still the zeroSSL certificate that appears in Webmin/Current Certificate

Do you want to expand and replace this existing certificate with the new
certificate?

EDIT : Very Strange, i test again to regenerate certificat with let’s encrypt on virtualmin and that’s work and Current certificate is now OK on virtualmin.
it never worked for several months and it works now, very strange

@DownPW go figure…

[DownPW]

yep very very erratic

In any case, thank you for the support.
