Description
Legacy FortiAPs are not able to join FortiGate after upgrade to 7.0.

This article describes how to process.

Solution
FortiOS 7.0.0 has reinforced strong cryptographic ciphers.
As a result, legacy FortiAP models using weak ciphers are blocked by default from connecting with FortiGates running FortiOS 7.0.0.

It is possible to disable  strong cryptographic ciphers using given commands.

# config system global
    set ssl-static-key-ciphers enable
    set strong-crypto disable
end
