Some time ago, I was able to connect to my server with the help of SSH and suddenly it stopped working.
I'm trying to order:
ssh -i "mykey.pem" ubuntu @ server-ip and Ec2 rejects an exception
Permission denied (publickey). When I tried to attempt the connection using the SFTP, the error was returned.
Error: Server Disconnect Message Sent Error: type 2 (protocol error): Error: "Too many authentication failures" Error could not connect to the server
I was then using the command in -v mode and here is the output. Can you help me, please, to solve this problem? I totally burn with heat about it.
