IPad mail sending through wifi has stopped working

Welcome to the community.

Have your tried restarting your Home Broadband Router - i.e., power off and back on. It is not unusual for home routers to occasionally/unexpectedly block traffic to some server resources; restarting the router often quickly and easily resolves this issue.

A simple router restart is an easy and non-destructive diagnostic tool.

I hope this helps to resolve your problem.

It solved the problem. It does drive me insane that 99% of computer problems are solved in this way but that is life.

You have rediscovered a centuries-old maxim: “When in doubt, reboot.” 😏

There are many causes - many of them can be determined from review of the router logs (which can be quite technical).

Please to learn that we managed to quickly fix your issue.
