Can I a Secure Port

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:
I ran this command:
No command
It produced this output:
No output
My web server is (include version):
The operating system my web server runs on is (include version):
Debian 9
My hosting provider, if applicable, is:
I can login to a root shell on my machine (yes or no, or I don’t know):
I’m using a control panel to manage my site (no, or provide the name and version of the control panel):
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot):certbot 0.28.0

Is there any way to secure the port 3000?

you get your certificate validating via dns or on port 80 or 443, and then you use it on whatever port you want.


Hi @VentoxProjects

there is already a valid Letsencrypt certificate.


  • check that vHost to find the two paths + filenames (key + cert/chain)
  • use these with your other port

You have a certificate already, you can use it for all ports at the same time, just follow whatever instructions are appropriate to install a certificate in your software. (if you need to know the paths, certbot certificates will tell you those). you should also add a --deploy-hook to tell certbot how to reload the certificate on renewal.
