Landonline slowness and screen flickering 21 to 23 March 2022

On Friday 18th March 2022 we installed new graphics cards to Landonline to support the Map Objects Replacement pilot for external users across 44 production servers. The installation of the graphics cards resulted in Landonline slowness and screen flickering for users as the load on each server increased.

The issues were first reported on Monday 21 March and continued through to Wednesday 23 March. On the evening of Wednesday 23 March the graphics cards were removed from the 44 production servers and performance returned to normal. 

Our service provider has identified the original configuration issue and will be trialling a new configuration on 5 of the servers before this is progressively rolled out across the other 39 servers. If performance issues are noted they will be able to quickly reverse the change.

An unidentified error has occurred

Signing customers in Landonline you may get error "Predefined message, an unidentified error has occurred".

If already using the latest version of Digisign3.1, these instructions will resolve the error:

A & I form printing unintelligible text

Some customers experience problems printing with the A & I form when their printed hardcopy has been produced with text in an unintelligible format.


Select the "Next" button on the CPP_S02 - Authority and Instruction Form to display a preview of the A&I form. 

Choose "Select All" from the edit menu, or press Ctrl + A on the keyboard.

Then, change the font drop down menu from the default Arial font to any other font.

UniPrint Client does not open

When the local UniPrint window/s do not open EG printing A& I forms.


Use option to “Save as” to a local drive then print that locally saved file. Note: you will need to select a suitable local-PC folder – if you try to save to a folder on the Landonline Citrix server an error occurs advising that location is blocked.

Blank forms are available if you require them: Blank A&I forms

Where the problem relates to the corporate version of Windows that you are using, the only workaround is to save and print locally. We are currently working on an upgrade to our UniPrint server and we expect that this will either resolve the issue or provide us with a better indication of the cause so that we can resolve it.

Saving a Fast Track Request

When a user creates a Fast Track request and the Survey Plan and Dealing do not have a status of Submitted or Lodged respectively the request cannot be saved. The request will need to be recreated and sent when the Survey Plan and Dealing have statuses updated to Submitted and Lodged respectively.
