Session for administrator refused

[tasmacher]

Since yesterday, we always get the error message:
"Session 1638260 for administrator /²‚| ( ) refused - administrator name not registered."
We will get this error frequently in other instances. How can I fix it? Or find out which user is affected?

Is this the administrator name: /²‚| ( ) ? If it is what a weird name!

One way of knowing which user is affected is by looking at which node missed its backup consistently assuming that this admin is related to a node.

The problem has done himself. The error no longer occurs. This is what we had on the other instances whatsoever. Unfortunately can no longer understand where the problem was. The administrator name is correct "/2, ()".
