Solved Handsets not registering

[jmp28]

I have just migrated a clients system from on Prem to 3CX cloud. Everything has completed successfully except for the handsets on the LAN where the on prem was located. There are handsets outside of the lan which connected immediately. I have managed to get one handset on the lan to connect but am struggling with the rest. I have factory reset the handset and removed the phone from 3CX. I add the handset back into 3cx but registration keeps failing. Initially I was getting the Block wan requests is on in the event log and I kept removing the ip address from the block list. I have also made sure the Block remote non-tunnel connections is unticked for the extension. I have checked the settings on the handset and can see it has the correct url for auto provision. I dont think its DNS as I can access the admin console from within the LAN and I have got one handset to connect so I am not sure what is causing the remaining handsets to not register. Any assistance would be greatly appreciated.

Check to see if you are using HTTPS:// and if it is the FQDN and not the IP that is in the Provisionlink, on the internal phones

Thanks Jed. I just worked it out. When adding the handset back into 3CX, I wasn't selecting direct connection. Once I realised the mistake, the handsets are now registering and coming back online.
