Yep, that was to be my suggestion too.

Move the box from the office (temporarily) and connect it direct to the router via a known working ethernet cable… if this works, then my next faulting step would be to check the cable between house and garden office. If through duct, does it pull nicely, look for evidence of chewing by a furry friend, or if attached above ground, has Edward Scissorhands been doing the gardening ?

yup pretty much the fault diagnoses route needed to be done. From the pictures it seemed that the tplink was in the same place as the router. But from the op's response i questioned it.

Also the fritzbox's with no dedicated wan port may use lan port one.. So HokkaHokka can you try the cable in lan port 2

So
Try the cable to the office in lan port 2 if that doesn't work do a local test as above ..

You might as well tempory move the unit to the same area as the router for testing

The port arrangement matches the 7530 AX, which is DSL only.

Clearning things up here:

Try the office cable into port 2 of the fritzbox. If that works its all good and ok if not follow the testing we've proposed

Sorry for not coming back sooner.
Thanks for all of the help.
I feel pretty stupid but swapping the plug from Ethernet port eventually sorted it.
Thanks again
