Recreate certificate after VPS reinstall


We are about testing VPS hosting AzuraCast (webradio streaming server) Docker type installation.
We already created the certificate with this procedure

As well we are in testing phase, we’ll have to reinstall VPS OS + AzuraCast.

As well as the domain name will be the same, is there a “let’s encrypt” certificate file or other, somewhere, to backup, or just I reinstall our VPS, install Azura, and recreate a certificate with the procedure like if it was never done ?

Thanks :slight_smile:

My domain is:
The operating system my web server runs on is (include version): Ubuntu 18.04 Server.
My hosting provider, if applicable, is: OVH (VPS SSD1).
I can login to a root shell on my machine (yes or no, or I don’t know):I have root access with Putty/SSH.
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):No.

Hi @Couin

that’s wrong.


Hitting the rate limit -> you are blocked.

Save your certificate outside of your VPS, so you can re-use the certificate.

Hi Dear,

Thanks for answer.

We do not plan to reinstall each 2 days, just reinstall one time and that’s all. If I understand the Rate Limites article, the limit is 5 / week (?).

The problem is that I don’t know at all where the certificate is on the VPS :frowning:
I don’t know how to backupt the file :frowning:

Edit :
I found these files on the VPS :

Probably. You should make sure azuracast and docker know to use those files (or, you can use commands like docker cp


AzuraCast member answered me that it’s not necessary to backup certificate, just request new one after install with their command :


wrong, they will hit the limit.

Hi Juergen,
I’m sorry but the “Rate limits” page still confusing for me :frowning:
I still really don’t undestand which limit exactly will be hit :frowning:
Azura says no problem, you say wrong, I don’t know what I have exactly to do step by step and this blocking me for VPS reinstall :frowning:

There are limits, so it’s always wrong to create certificates again and again. Create one certificate, then use it 60 - 85 days, then create the next.

Sorry buyt it still confusing for me :frowning: Limit of what exactly ?
I don’t wont create again and again , just I have only one reinstall of VPS to do, I can not wait for 2 / 3 monthes :frowning:
How can I re-use the certificate I actually have ? Restore files I listed below is enough ? Or There is something somewhere else to backup before reinstall VPS ?

Thanks :slight_smile:

The main limit concerning you is the limit on identical (same domain set) certificates: 5 certificates per week.

And tangentially you might be concerned about the limit on certificates per registered domain: 50 per week.

Maybe the limit on failed validations, too? That’s 5 per hour, though.

I really don’t know :frowning:
I don’t plan to reinstall VPS more than 5 times in a week .

the duck is lost in space :frowning:

So it’s fine, you can reinstall with a new certificate.


And in the case of I would backup and restaore the first certificate, do you know if there are some others files than theese I listed below ?
Thnaks :slight_smile:

Hi :slight_smile:
I tested with a another VPS and domain name that I already made a certificate.

1st test :
Backup files listed below.
Reinstall VPS + AzuraCast
Restored files

2nd test :
Reinstall VPS + AzuraCast
Create a certificate like if it was the firt time I do.
Result OK .

I think it will be OK with the same steps on the radio VPS.

Thanks :slight_smile:

You should ask the azuracast community. I’d go with backups of /var/lib/docker, but that’s almost certainly an overkill.
