I just did a fresh installation of Magento 22.214.171.124 and I am seeing some very odd behavior with the customer login form.
In Chrome (version 36) the login form does not work. I am just redirected to the login page. There is no error message. However, when I open a new Incognito Window, I am able to login just fine. Thinking this was a cookie problem, I cleared out all my cookies from the browser and tried again and I got the same results. In both cases, I am able to login to the admin panel without any issues.
I have also tried this in Firefox . On Firefox its work properly .. thank you
