Is There Any Workaround For The 255 Code (error)?

Method 1

The 255 code (error) appears if the RSA keys are missing.
a. Create the RSA key.
b. Insert the public keys in the authorized files.
c. Try working on your system.

Method 2

Firewall restrictions often cause the issue that you are facing.
a. Check the IP tables using the command – iptables -nL | grep xx.xx.xx.xx.
b. Remove the firewall restrictions that you find.

Method 3

Change the permissions in the following way using the command line –
a. chmod 755 /home/user.
b. chmod 700 /home/user/.ssh.

Note – You can get the error if the remote server is down. So, in that case, you will not be able to do anything.
