FG disconnected from FMG after uploading new license file

[aagrafi]

Hello,

My FMG was running with demo license and has an FG added. Everything was working fine. I registered a valid FMG license and after I uploaded the new license file to the FMG, the FG appears to be disconnected from the FMG. It seems the FMG cannot establish a tunnel to the FG. Do you know why this happened and what can I do to bring the FG up again?

Thanks

with a new license the FMG will have a new SN. use: exec fgfm reclaim-dev-tunnel all to force the FMG with SN to take over the fortigates.

Cheers

I tried this command, but the FG still appears to be disconnected. Is there any cli to debug the mgmt tunnel?

Thanks
