I had a smilar problem with a home I owned and I solved it by talking with my agent on what I could do to get it fixed. Ideally you don't want to have your insurance canceled. They usually send you notices and give you a heads up prior to cancelation.
Then I would get a phone there.
Then I would sleep there at least one day.
That may help your cause.
I would contact a local insurance professional to help with this answer and to save time and money.
Try not to say you aren't living there, unless you really aren't staying there at all.

You want to get a Vacant Home Insurance Policy immediately. These can cost 2 to 5 times the amount of your regular insurance policy, but often can be purchased monthly.
You want to do this now, because banks sometimes send out representatives to determine whether the home is vacant and if it is they can change the locks and notify the bank that the home is vacant. The bank may then take out insurance to insure that vacant home and send the bill to you or worst call on your loan immediately.
Coverage for a vacant home will be more restricted than regular home insurance, covering standard perils such as fire and wind, but not perils such as water damage due to frozen pipes, glass breakage or vandalism
Home insurance companies typically require you to contact them and request an endorsement or a special permit for a home that will be unoccupied for 30 or more consecutive days. In some cases, you may be charged for the permit or endorsement.
Some insurance companies allow homes to be unoccupied for 60 days before requiring notification. The time limit is stated in the policy.
