Cannot access my Roundcube email

I believe it started yesterday, 12/31/17, I started getting a message from my phone email client that authentication failed. I figured it was just a temporary outage so I ignored it for a while. Today, 1/1/18, I continue to get this message so I tried to log in via my computer's browser. I get a message from roundcube webmail that my login failed. Nothing has changed on my end and I have not recently changed my credentials.
