Can't manage my router via app or website anymore

[Spaceboy881]

For about two weeks now, I lost the ability to manage my router through the My Fios app or via Verizon.com. It used to work great but now I get the following errors:

Website: "There was an error in retrieving your router information."

App: "SSL Certificate Error"

Anyone else having this or know how to fix?

Have you tried rebooting router?

[Spaceboy881]

Yes, rebooted multiple times and no luck.

Can you log in directly by typing myfiosgateway.com or 192.168.1.1 into your browser?

[Spaceboy881]

Yes I can only access via the IP address.

Maybe try hard reset by holding down reset button. Deleting and reinstalling app. Then try again. 

Also are you trying to configure something specific in the router?

[Spaceboy881]

What will doing a hard reset do? Will I have to setup everything again (e.g. SSID, PW, parental controls etc?)

[Edg1]

Yes but worth a try. And what exactly are your trying to manage from the verizon app?

[Spaceboy881]

I mainly want to be able to do parental controls

Is it a newer router?  If so I'd definitely hard reset.
