in USG FLEX H Series

So far we have always accessed the USG/ATP series UTM using the php (8.2) function

ssh2_connect($firewallIP, $port, $callbacks);

By doing the same with USGFLEX700H we can't connect and get this error:

"ssh2_connect(): Error starting up SSH connection(-5): Unable to exchange encryption keys"

    Hi @noc_aba,

    "Unable to exchange encryption keys" looks like your code cannot exchange encryption keys with USGFLEX700H. You might need to check if your PHP code, libssh2, PHP SSH2 Extension support the new encryption and key exchange methods.
