iPhone will not connect to BlackVue DR550GW

When using my iPhone I select; settings, Wi-Fi, "BlackVue", I select and connect to "BlackVue". When using the BlackVue App (Ver 1.3). I open the App, I select Wi-Fi, and the App says connecting and then times out. Then it says "Could not find the BlackVue".
I am unable to connect to my DR550GW-2CH using my iPhone.
I am using the latest version of the BlackVue App, 1.3 and firmware for DR550GW. This used to work but now does not.
