Connecting to Apple server
i am using iphone Xs Max with a 64GB. Memory was full. I switched the phone off. Switching it on again i noticed the Apple service was down; no display of contacts, sms, other services are also down. I have tried many times to sign into Apple but the phone keeps telling me that - Verification Failed - "There was an error connecting to the Apple ID server". Meanwhile, my ID and password are correct. What should i do
