Webmin - Convert Test Certificate to Production Server


Have been using LE on Ubuntu 16.04 via Webmin.

I originally tried a “Test” Cert and now want to change the LE Cert to a Production version.

What is the best method to achieve this?

Any assistance appreciated.

Thank you



Hello @GetSmarts

how did you do that? With a client like Certbot? Or is this a Webmin-Feature?


Just create a new certificate and make sure to select the Real server and not the Staging server.


Thank you very much for your response.

I have tried to do that and in doing so I get the message as follows:

Error signing certificate: 429 Error creating new cert :: too many certificates already issued for exact set of domains: soc01.xxxxxxxcentre.com.au: see https://letsencrypt.org/docs/rate-limits/

I have read the rate limits and do not believe that we have surpassed any limits.

So a little confused.

Thank you again.



It was done directly via Webmin

Thank you.


You have issued exactly 5 of the same duplicate certificate for your “soc01” domain within the last 7 days.

The means you’ve hit the Duplicate Certificate limit as written on https://letsencrypt.org/docs/rate-limits/ . The first was on 2018-06-13 04:33:07 +0000 UTC, so you’ll be able to issue the next one exactly 7 days after that.

One workaround is to issue a certificate that would not count as a duplicate, e.g. if it had both soc01 and soc02 as domains on it.


Thank you very much for your advice.

That has fixed the issue.

Much appreciated.
