Website sign in error code 105

Hi 

I can sign into my account via the 1p website using the scan QR code method, but on my iPhone I need to use the old method using my 2fa code, Im entering all details correctly, when I paste the 2fa code and press enter its just continuously loads and eventually says "something went wrong", please check your internet connectivity, something like that!

Also see an error code 105.

My internet is fine, Im trying to login on the safari browser.

Any ideas?

/Update I disabled iCloud private relay and I could log in. 

Having that enabled hasn't been an issue in the past though.

Thanks
