I had the same issue as Mr. Singh at 11:30am pst, never did get in. I had just raced at 9:00am pst on the same machine, same browser, but different team. all settings the same. I was able to race from my phone at 11:30 so not a loss, but an annoyance. I cleared my cache and restarted my browser several times, I did not restart my machine however. Hope this helps.
