Admin Process: There was error reading the request document

Hi all, I am facing with odd console warning:

Admin Process: Received the following error performing a

Update Server’s Protocol Infomation request on Hub/MLS (File name: names.nsf): There was error reading the request document.

This error were posted to this forum many times but I’ve found only one tip to re-sign names.nsf with Server ID and it didn’t help me.

I don’t understand reason because my names.nsf’s ACL contain manager access with all roles for the server Hub/MLS…

Please advice me.
