error message when site tries to load

I usually use wordpress on my dell laptop. I was trying to log in from my iPad instead. I had changed my admin name & password after some hacking attempts a few months ago, but hadn’t used my ipad to actually post anything since the change. In trying to make the change on my ipad today, something happened so that now my site won’t load at all, anywhere. When I try to load my site, it simply says “error.”

My site is currently self hosted. I was originally on wordpress.com. I switched to self hosted about a 9 months ago and have been regularly using jetpack on my current site.

My current url is: technologyinearlychildhood.com.

My former url was technologyinearlychildhood.wordpress.com

I’d love some help with this.
Thanks,
Karen
