Problem connecting to the server

Sorted. When I plugged in my iPhone it was syncing with my Music library, but there were 3 corrupt files no longer on the NAS. As these no longer existed, it was looking where they used to be - on the missing NAS.

Thank you.

Router is brand new from the broadband provider, although I appreciate that means nothing!

I've had issues with my broadband dropping regularly since I started with my current provider about 2 months ago, and they've been out to test external and internal wiring and the router, so it should be OK.

I can pin down when it happens, though:

When I connect my iPhone via USB Photos opens and, if there are any new images, I'll import them into Photos and delete them from my iPhone. Easy.

A minute or so later, the pop-up appears.

I spoke with Apple Support about this, and they don't understand it either - even though they've watched it happen when screen sharing.

They told me to ask Synology..!

Sorry, I thought I'd replied earlier...

I've determined what's causing this issue, but I can't find a solution - even with help from Apple Support.

Essentially, what is happening is the only time (so far) I get the pop-up is shortly after I connect my iPhone to my iMac using a USB cable.

Photos starts up (as I've set it to do) and, even if I do nothing else, I get the pop-up about a minute later:

This happens every time and, to be clear, this is the serve name of the NAS before I reinstalled DSM and renamed it.

Thank you.

I thought I'd replied to your message, sorry....

Anyway, it's brand new but, because I had broadband speed issues, the wiring from the exchange to the house, the internal wiring and the router have been tested, and all work fine.

What's puzzling me is this happens when I plug in my iPhone, but not my iPad.

Thanks for the suggestion, but sadly that didn't work.

This seems to popup shortly after I connect an external device, e.g. my iPhone, which then opens Photos.

Puzzling.
