We created a new install of freepbx 17 and restored from freepbx 15 backup. Everything seems to be working now, except for the REST buttons on the Sangoma S705 phones. Whenever you press them, it just says Loading, Please wait, and nothing happens, then it goes away and you’re back to regular screen. The old pbx was chan sip extensions and are now converted to pjsip. I don’t know if that is relevant or not. Also the old setup, phone apps were http, they are now https, but port 1443 is forwarded to the pbx.
What do I need to watch for in the log lines?
The pbx is up to date.
