I sent a reply to your private message. Just to be clear, instant ink is working, it is just the other web services like “scan to email” that are not working 

[Jay_G24]

Just wanted to make sure the account is not giving any error

Try and set up scan to email again, refer to -https://support.hp.com/in-en/document/c03862727( The product may be different, but the steps remain the same) 

And, also try and use a different browser to enable webservices.

Hope this helps!

Keep me posted!
