PuTTY Fatal Error: expected key exchange group packet from server
I had this same issue and to fix it i change the key exchange algorithm.
In putty settings under connection->ssh->kex I moved Diffie-Hellman group 14 to the top of the list and Diffie-Helman group exchange to the bottom. this solved the issue.

You can enable logging of sshd which can give you more details about the error.
To enable logging:
Edit etc/ssh/sshd_config file and add the following line
LogLevel DEBUG2
Reload sshd config:
systemctl reload sshd
Debug message will be logged to the file /var/log/secure
tail -f /var/log/secure
