Lost certificate after reinstall

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is: dipodesign.synology.me

I ran this command: formated NAS due to stability issues

It produced this output: lost all certificates

My web server is (include version): ?

The operating system my web server runs on is (include version): DSM7.1.1

My hosting provider, if applicable, is:

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):
interna controle panel synology

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):?

is there a way to get the certificates back?

From a backup?

There is a way to get the certs but if you don't have their matching private keys it won't help.

Just request a new one and go from there. In fact, you've gotten a couple already today so you should just use one of those


thanks for the response
but i can't add an new one cause i've reached the limit on my domain

I only see 2 of 5 allowed per week for that domain so you should be allowed 3 more this week. But, sometimes the logs are behind so maybe you are rate limited now.

What went wrong when you got the ones earlier today? Trying yet another one wouldn't work any better.


lost the https
got message again that the connection was not secure

that and a error in router setup

Are there logs that we can see? It would help significantly.


Do you have a backup of the certificate?


Sadly I don 't have a back-up made

Then you won't be able to get the certificate back in a usable form. The cert itself is public information, and is logged in certificate transparency databases. But the private key is, well, private--you had the only copy of that. If you destroyed it without having a backup, nobody else can get it for you, and that means the cert you can download will be worthless for you.

It doesn't look like you've hit a rate limit on cert issuance; as Mike said, you've only issued two within the past week and you're allowed five. But there are other rate limits, and the one you may have hit is on failed authorizations (which resets in an hour).


I'll try this weekend again till then no time
