Use certificate with 2 'domains?'

[phirephoto]

So I have a hosted PBXIAF, hosted in the cloud. I have obviously https://IP.ADDRESS:5001, https://mydomain.3cx.us:5001, and https://www.mydomain.com:5001 . Starting just now (24 hours after deployment or so, I can no longer access mydomain.com:5001. I get:

Your connection is not secure

The owner of www.mydomain.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox may only connect to it securely. As a result, it is not possible to add an exception for this certificate.

www.mydomain.com:5001 uses an invalid security certificate. The certificate is only valid for mydomain.ca.3cx.us. Error code: SSL_ERROR_BAD_CERT_DOMAIN

I logged into 3cx portal, but download certiifcate does nothing, and not even sure what I'd do with that.

Any suggestions?

to my knowledge, to change fqdn you will have to reinstall.

Hi,

I don't want to change the fqdn - well, technically, I'd love it to be pbx.mydomain.com , but I see no way to do that, it sticks to the 3cx.com domain..?

Ok so your statement is incorrect. You can still access https://www.mydomain.com:5001, you are just getting a certificate error which is to be expected. The certificate you were issued was for https://mydomain.3cx.us so accessing 3CX by any other URL is going to cause a mismatch. If you want to use your own FQDN you can. You need a PRO or ENT license and you need to follow the guide here:

Hmmm.. This is just a server for me, so can't really justify a pro license. But no, I literally CANNOT access my site in Firefox. Looks like IE will let me but Firefox won't No "Ignore" or Continue option).

To unstick the FQDN, open a ticket at 3CX support.

Can my fqdn be www.mydomain.com ? That's what I selected during the install, but it reverted to the 3cx.us domain...
