I manage two clusters, Cluster A and Cluster B connected over a WAN.
Cluster A has a publisher and 8 Subscribers
Cluster B has a publisher and a Subscriber
• CUCM in cluster B is UNABLE to backup to SFTP server in Cluster B network. Error message is "update failed : unable to access sftp server. Please ensure the username and password are correct"
• CUCM in cluster B is able to backup to SFTP Server in cluster A network
• CUCM in Cluster A is able to backup to STFP server in cluster B network
I use Solarwinds as SFTP server solution. I also tried Coreftp, but got the same result.
I have checked to ensure there are no restrictions on the network either by firewall or otherwise.
What could be causing this? Are there troubleshooting methods I can try?
If you don't see the request in the SolarWind SFTP server monitor that would mean that the traffic never gets that far. As other have pointed out make sure that the traffic for the SFTP server is not blocked by anything along the way or in the server software firewall.
For reference this is what we get in SolarWind SFTP server monitor when I update the configuration of the backup device in CUCM DRS.
The first line with the failed login is for not typing in the password on the backup device definition again before pressing save.
Hello @Wilson Samuel ,
Thanks for your response. As stated in my original post, I already tried Coreftp. I will also try WinSCP and provide feedback.
Try below troubleshooting steps:
1. Are you able to ping SFTP server from CUCM Cluster B.
2. Do you have any access list or firewall that is blocking SFTP port between CUCM Cluster B and SFTP Server?
3. Disable any firewall on antivirus software on the machine where Solarwinds SFTP is running and try it.
4. Make sure you have correct Username and Password configured.
Hello @Vaijanath Sonvane, Thanks for your response.
1. Yes, ping between the publisher and the SFTTP servers are successful.
2. All Firewalls and antivirus were disabled temporarily . It still did not work.
3. The same username and password were used on the Publisher in Cluster A and the backup was successful. The credentials are fine.
Do you have the path correct as well? I've seen issues where an incorrect path gave this same error. To save in the SFTP server's root, some want the path specified as "\", some want ".\" and I'm sure I've seen other variants. Try connecting to the server with a command line SFTP client and set the path to see what works.
