Internal server error

I have run into this a couple of times. 

I go to login to Okta and after entering my email address it does not proceed to the Push notification, instead the page refreshes and there is a banner at the top that says, "Internal server error".

I tried:

• Quitting and restarting the browser.
• Emptying the cache.
• Opening a new tab and a new browser window
• Opening a Private window
  • This works
• Logging in from another browser
  • This works
• Logging in from another machine
  • This works

Obviously something is "stuck" and it does not want to proceed past the first step. I finally found a solution, but it is weird...

I cleared out my email address and typed in "alincoln@tammaninc.com" and clicked the button.

Instead of the "Internal server error" message it allowed me to proceed to the next screen. I clicked the "Login as another user" button and went back to the initial login window. I replaced Abe's email address with my email address and then I was able to login normally.
