Can i use Certbot on windows server 2016

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., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:
it's posible to cmd : ping

I ran this command: none

It produced this output: none

My web server is (include version): windows 2016

The operating system my web server runs on is (include version): windows 2016 standart

My hosting provider, if applicable, is: no-ip

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 - using RDP

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): none

contain(s) the right IP address. Additionally, please check that
your computer has a publicly routable IP address and that no
firewalls are preventing the server from communicating with the
client. If you're using the webroot plugin, you should also verify
that you are serving files from the webroot path you provided.

There are several Windows ACME clients that can do this job.

hi. thanks for the quick response.
i install Certbot and run it and get some *.pem in c:\Certbot\live\


but i need to create file *.cer + *.key that i can put wher my ServerMailr is.

how can i convert thos files to those i need?
hoe can i check if my is noe https?



Hi @mazluta

I don't know how that program works.

But it looks that you only have to copy / rename these files:

fullchain.pem -> fullchain.cer
privkey.pem -> privkey.key

Try that.

If that doesn't work, check the documentation to see, which file format is expected. With OpenSsl, converting should be possible.


thanks. i will try it


Please keep in mind that the files in live are LINKS and not normal files!
