Can't log in to the cms when I'm on my phone

Whenever I enter my credentials on my phone, it simply reloads the page, but works when I’m on my laptop. I use safari in both. It started happening around two weeks before the power outage in HIZ, and I cannot still access anything on my phone. Is there a way it can be fixed?

I can log in to the CMS on my phone. I tested it with Chrome and Firefox.

Have you tried clearing the cache/cookies and trying again?
