Problem connecting to a computer

Hello,
I am unable to connect to a remote machine via ssh.
I get this error message :

Equivalent Command: ssh -4 -o ServerAliveCountMax=3 -o ServerAliveInterval=15 -o ExitOnForwardFailure=no root@xxx.xxx.fr
10:58:33 Connecting…

10:58:33 Abnormal Disconnect
Thanks for your help.

It seems your remote host require one of diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 algorithms, but unfortunately, they were deprecated and disabled by default.

Please edit your profile settings, and set KexAlgorithms to +diffie-hellman-group1-sha1:

I would recommend you change to other more secured algorithms at server end once you get a chance.

Kindly Regards,

Yang
