Hello,
You can check the network connection if it is different. If it is the same, you can check the connection at this time.
You can check that your Ipad is up to date and that the Remote Desktop application is up to date.
You can restart the iPad.
Otherwise, you can try using another remote desktop app (e.g. TeamViewer or AnyDesk) to check if the problem is app specific.
Sincerely,
