Cloudy but fine

I have made a Fullers London Pride clone about 6 times in the past.
Basically just pale malt, medium crystal and bittering hops (posted recipe in another thread). Always came out really good and very clear. I had cooled 3 and cubed 3 and all came out basically the same.
Current one (cubed) has now been in the keg for over 2 weeks, tastes fine but it is cloudy as buggery.
Everything went as per previous brews and numbers were good. Obviously some variation somewhere.
Any ideas on most likely causes for the cloudiness?
Cheers

Cheers Gash,
Probably sat on the yeast a few days longer than normal while an IPA finished off, thought that would help if anything, both were cold crashed for for 3 days.
Used S04 yeast, cracked on after 24 hours and finished reasonably quickly as normal. Ferment temp was 19 C. Funnily enough had a couple of issues with the IPA and dry hopped with about 150g and that is crystal clear.
Looks more like a cross between a Coopers pale ale and a NEIPA. So dont think it is a chill haze.
Drinking one now

Could be mate.
Just in the middle of brewing another one as I type. Cloudy one is nearly finished
This will be going in the cube as well (IPA and a Dunkel still in the fermentation fridge). Will see what happens.
Got to get ready for Christmas and New Year......
