Issue: macOSx client won't sync - web client works fine

Hi guys

I’m having some issues, since I’m on a linux shared server it doesn’t allows form much “tweak” but I’ve manage to get nextcloud up and running.

It works flawlessly with photos - my main reason to try this out - everywhere.

the issue is that some type of files, not all of them, won’t sync with the client on mac, but the same files if uploaded thru the web it works fine! odd…

some file types that signals forbidden are indesign ones, some downloaded photos from the web (?) and zip files with after effects - non zip also won’t upload ae files…

is there something on the settings that i’ve missed? server?!

thanks for some help provided or thoughts that could help me…
cheers!
