SSL issue, provisioning port only..

[rgoldman]

Hi, I can access my dashboard fine. However I'm trying to provision a phone.. getting this error message..

This site can’t provide a secure connection​

<domain> sent an invalid response.

• Try running Windows Network Diagnostics.

ERR_SSL_PROTOCOL_ERROR

I tried the manual PbxConfigTool -renew-certificates, no errors, no luck. I can access the dashboard fine, so I don't think it's an SSL cert issue, seems like something in the web server config.

Anything else to try before I reinstall? Thanks

Hi!

For sure I would want to see the information Saqqara mentioned too.

Also though, you say you can access the Management Console fine, but from the same browser if you paste a provisioning link of an IP Phone you are getting this error?
For these 2 links, are you using the same IP/FQDN and Port?

18.0 Update 2 (Build 314)
Debian 10
On Prem DIA Static IP - no nat
Polycom VVX250 - latest supported by 3cx firmware

See attachment on the firewall checker, but there is no hardware firewall on it. Now I’m thinking it may have something to do with that because I did remove a SonicWall that was in transparent mode.. I’ll have to check when I get back to the office later today or tomorrow, I’ll post back.

I have a couple phones that are registered and working fine, so that threw me off. But I’ll post back when I troubleshoot more. Thanks!

Are the phones running the required 3cx firmware - https://www.3cx.com/sip-phones/polycom-vvx/ Step 1

One the provisioning tab, are you using the 3cx lan ip address under 'Select Interface. Step 7
