Desktop Client Access denied State token does not match

I have just installed Nextcloud using snap on to my Ubuntu home server on localhost, I then used dydns to get my nextcloud to show on a domain name. This is so far working and I can access my nextcloud via any web browser both at home and outside. I have also installed nextcloud mobile app on my phone and entered the domain name and this is also working perfectly! However, I have just downloaded the Nextcloud Desktop Client unto my Windows 11 and done exactly the same thing, entered my domain name but it keeps saying Access denied State token does not match! Im not sure what im doing doing wrong. I have created Device & Sessions in my security, please can anyone kindly advise me on what I am doing wrong please.
