Update: This issue is now resolved.
For a subset of clients, our team has identified an issue causing Datalink to produce an error which is preventing Demographic and Attendance file transfers.
(The error produced by Datalink is: Problem establishing SCP connection to host: Key exchange failed. Requested service is not implemented.)
If you are affected by this, there is a workaround that you can use if you wish to upload and process your files while we address this issue. You can use a file transfer program to move your files to your usual SFTP location. If you are affected by this error and have questions about this workaround, please contact our Support team.
We are working to correct this as quickly as possible.
