Invalid SSL certificate when trying to login via my WP app on my phone

Hello,

When I am trying to login to my admin via the Word Press app on my phone I get the following error.

If you usually contact this site without problems, this error could mean that someone is trying to impersonate the site and you shouldn’t continue. Would you like to trust the certificate anyway?

However, I can login via a computer just fine. Is there something I’m missing? Details on the error are as follows.
