CSRF check failed when logging into pfSense

[alanper]

Whenever I log into pfSense I get the following alert:
"CSRF check failed. Your form session may have expired, or you may not have cookies enabled."
There is a "Try Again" button below the message, and clicking it loads the dashboard page successfully.

I am using Chrome and have cookies enable.  I have tried different OSs (using Chrome) and both give the same error.  Interestingly, when using a Chrome window in incognito mode it logs in successfully every time.

Anyone seen this before?

Nope, and have been using Chrome with pfSense for years.

I see now and then if login too quick with firefox.. but if you wait a few seconds it works fine.
