I suddenly get {email address} doesn't have access to Jira on datafloat.atlassian.net

[Jason Norton]

I have been using a Jira kanban I created when I started working at this company 6 months ago.
  I have over 700 tickets with various details and attachments that I access everyday to manage my workload and project planning.
  Suddenly, when I go to log in, I get this message:

   (my email address) doesn't have access to Jira on datafloat.atlassian.net.

There are three different email addresses with varying rights that I can use to access this and now they all get the above response.

   I am using Chrome.

   I have tried using an incognito Chrome window, Firefox, a different computer and all the same results.
   Any ideas on how I can get back on that board?
