Saving Data Failed

Hi, new user so please forgive me if I'm asking a question that's been often answered. I have searched the forum without success for some answers already.

I have a Profilux 4 connected to a PAB6E and I'm attempting to connect/control a return pump. I am continually receiving the Saving Data failed message. This has been happening all night whenever I attempt to change settings.

I have cold rebooted, accessed the device by web-browser, on my Mac and Ipad Pro and also using the IOS app, same results.

The app always finds the device but I just don't seem to be able to make/save any adjustments.

Any help appreciated, thanks, Havey

Solved. The solution was to reinstall the Profilux 4 as a local device and manually set the wireless IP address rather than have the IP selected automatically.
