Hi, Brand new install of 3CX. Using Fanvil X4 phones. I'm struggling to auto-provision the phones and it seems the issue lies in the fact 3CX won't respond on HTTP port 5000 for the provisioning link if I use https://22.214.171.124:5001/provisioning/ID/mac.cfg - I get the CFG file given to me via a browser. However... if i use http://126.96.36.199:5000/provisioning/ID/mac.cfg - I get 403 forbidden nginx This is all done on a local lan. it looks like this fresh install of 3CX does not want to work over HTTP on port 5000? What am I doing wrong?
