Freepbx 17, I am getting an SSL Error when registering Endpoint

FreePBX Endpoints
1

I have created an instance in Vultr and restored a backup from version 16.
It all seems fine, however, I get an SSL error when trying to register an endpoint.

[2024-08-08 16:22:30] WARNING[2158]: pjproject: <?>: SSL SSL_ERROR_SSL (Handshake): Level: 0 err: <167772353> <error:0A0000C1:SSL routines::no shared cipher> len: 0 peer: WWW.XXX.YYY.ZZZ:53192

The certificate is selfsigned, and is up to date. Endpoint is Grandstream, using TLS 1.2
Can someone give me some pointers?

Thanks!

start by turning it off to verify connection, an example is here:

Do you still have your version 16 that works active? If so and you can get a wireshark capture of a successful registration from the phone and compare it to the failing registration you can probably figure it out. (or post it here and someone else can)

I think I found the issue. My deployment didn’t have a TLS certificate selected in SIP > PJSIP Settings, I switched that to the “default” self signed certificate.
While I was tweaking I don’t remember rebooting the server, but this morning while doing something else, I had to. Now it works. So I guess chaning that parameter needed a server reboot.
