How do I fix "Device Timed Out" error when importing from iPhone?

I was never able to complete a "long" scanning session (multiple scans) without receiving this error.

WHY? How can I avoid this error?

Sounds like the iPhone is nodding off between scans.

I'm guessing that you need to up the iPhones auto lock time during a scanning session.

iPhone is using 85% of the Total Drive Capacity

MacBook Air is using 88% of the total drive capacity

I can not speak to iPhone and suggested Empty Space

But the MBA I can

It’s good computer practice to keep at least 15% to 20% of the total drive capacity empty to avoid unintended consequences which maybe Part of the Over Issue

It would seem reasonable to believe, a similar need would also apply to an iPhone

Outside of what has been mentioned

Is there a Commercial VPN involved and configured on either or both devices ??

Normally, a VPN would slow down internet speeds by about 30% and yes interfere in the iPhone Scan to Computer process

What battery level is the phone at when attempting this?

How full is the iPhone & the Mac?

Good questions by @ BDAqua >> re-Empty Space on both devices and battery levels

Using a Headless M4 Mac Mini with Sequoia 15.5

Using an iPhone 15 Pro with iOS 18.5

Used Preview on the computer and Preview application

Both Devices are adjacent to one another

Same Wifi Network , bluetooth ON on both devices

Plenty of Empty Space on both units

Plenty of battery on iPhone

In Preview , File >> Import of iPhone << Scan

Immediately, the iPhone Camera came to life

Yes, 1 page but maybe you need to Plugin the iPhone to Charger for multi page Scanning ?

This is a question that has a specific answer, which - may be - only Apple knows: please do not ask to log-out restart format delete recharge reinstall the OS do this do that etc. if you do not know the exact answer. I have made plenty of reasonable, unreasonable, absurd and random attempts before asking this question here. Apple should explain why the connection times out when all the listed requirements are satisfied.

You can’t make a statement that it has a specific answer without knowing what it is, so well wait for the reveal.

Respectfully, " no tongue in check " remark

The presented facts ? speak for themselves

Free space:

• iPhone ~ 20GB free (out of 128 GB)
• MacBook Air: 30GB free (out of 256 GB)
