I had to change the public IP will the certificate for may domain still work?

Please fill out the fields below so we can help you better.

My domain is: sip.iai.int

I ran this command: none yet

It produced this output:

My sip server is (include version): 3CX

The operating system my sip server runs on is (include version): latest

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

So, I had Elastix before and it run smoothly, but I have upgraded to 3CX and we have a new sip trunk provider, our national Telephone company ANTEL. It was a package with sip trunk + optical fibre + modem + new public IP.
So I want to know if I can still use the certificate I was using while sip.iai.int still resolved to 190.64.77.165. Now we have sip.iai.int resolving to 200.2.59.206.
I hope my question is clear enough. Still use old certificate, create a new certificate?
Regards,
Alejandro

Hi @AlejandroF,

A Let’s Encrypt certificate refers to the domain name, rather than the IP address. The browser accepts the certificate as valid if the domain name that was used to access the site matches a domain name listed in the certificate. So, you don’t have to get a new certificate when you change IP addresses; your existing certificate will remain valid.
