After migration from 10.1 to 10.5 , our server is facing with the SFTP.
Example :
We migrated from the Nonagon to gallium server.
In Gallium server now SFTP is not working ,
I created the new server alias and user alias , but when am testing the user alias , am getting the error as [ISS.0147.9011] Test of SFTP user alias MessageHandling failed. Details: Auth fail
For information : Both SFTP and server is gallium only
did you remember to apply latest Fixes to both the instances during the migration?
There were some issues with JcSch lib used for SFTP connectivity which have been fixed meanwhile.
You might would like to upgrade the SFTP connection and change the
SFTP host alias to version 2 and change the โMin DH Key Sizeโ config to 2048. Check if this works.
