DNA backup error

Hi all,

 

I have configured DNA backup (Remote Host & NFS). DNA system version is 1.3.0.147.

Remote linux server tried were Ubuntu 20.04 & CentOS 8.2 and access to folders was ok.

At the end of update (both All data and without Assurance data) was this error:

BACKUP.FINALIZE_BACKUP FAILURE EndpointConnectionError
Then I found this bug:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvt64548
 
On linux server changed max parallel logins per user to 100, but the same result.
 
So what Linux version to use for backup ?
Can this issue related also to this DNA version ?

Issue resolved!

Firewall monitoring showed all SSH sessions allow, but actually security profile in firewall policy denied SSH at the end of backup process (~90%), because of so many parallel SSH sessions.

How did you solve this even tho you allowed max parallell logins to 100?
