Question

hello,
we're connecting to sap using logon groups and randomly we get this error

i can't figure why sap gui is trying to connect to 127.0.0.1 ???
and after a while it works without any modification... very strange no? but annoying!
if i do not use logon group and connect directly it works but it is not what i need to do.
any idea?
regards

Answer 1

hello,
thanks but configuration of logon groups is very straightforward...
my logon group contains my two application servers.
what else do i have to check?
regards
