I recently installed NBU 7.6.1. My backups are running except for a few clients that cannot connect. However when I try to restore the all clients cannot connect to the master server.
I tried to put the SQL Credentials manually and that does not work.
Solved! Go to Solution.
do as Marianne advised.
you can use telnet cmd from master and client on port 1556
telnet client 1556
telnet naster 1556
