Welcome to the community and thank you for posting. I am sorry to hear you have no connectivity due to a power outage. If you could please go here, click on system status at the top of the page, and inform me of what the System State Code is, so I can verify what kind of error you are getting in the modem.
You may want to do the same thing Hardy asked the OP to do and post your state code.
Edit: It may also have something to do with the message posted on the home page:
Some HughesNet customers are unable to access their service due to an issue with a network provider that carries a portion of our Internet traffic to our satellite gateways. Our engineers are monitoring our network and working closely with the provider to return service to normal as quickly as possible.

I don't think the HN reps are here today, and they will be out tomorrow -- you may need to use the phone or the chat help.
*I am not a Hughesnet employee or representative. This is a customer-to-customer tech support community, and I am a customer.
I am having the same issue, did you find a resolution??
