We have a client that is experiencing an add-in initialization error: "Microsoft.Dynamics.GP.OnlineServices.dll: Unable to get valid config from serialized string. Client proxy can not be configured properly..."
They have had three users receive the error in the last two days. Deleting their user out of GP activity and their login from the terminal server allows the users to log in, but I can't find a cause for the error. I have seen a suggestion to remove Online Services or repair the GP install, but since the error is received intermittently and by different users on the same terminal server it doesn't seem like it could be a problem with the installation.
Thanks,
Marilyn
