Troubleshooting
Problem
The portal backup using sftp fails.
Diagnosing The Problem
The following error stack is seen in the admin container of the portal www pod. For example: In port-lx-abc-www-0_admin.log :
[ syslogd stdout] 1897 id date:49: backup_site: Command Started: /opt/ibm/bin/backup_site -ib
[ syslogd stdout] 1897 id date:49: backup_site: Currently installed sites (pre-backup):

[ syslogd stdout] 1897 id date:50: backup_site: Command Finished: /opt/ibm/bin/backup_site -ib with RC 16
Resolving The Problem
The error message indicates that the SFTP server is rejecting the connection attempt, and the reason given is "Permission denied (publickey,gssapi-keyex,gssapi-with-mic)." This suggests that the server is configured to only accept connections using public key authentication or GSSAPI methods.
If you are trying to connect using a username and password, you may need to check the server's configuration and adjust the authentication methods allowed.
Here are some steps you can take.
Please login to that sftp server and open this file /etc/ssh/sshd_config then make sure PasswordAuthentication is set to yes then save and restart the server.
