Wordpress Weird cache issue with my customer login page

Hi,
I'm seeing a weird cache issue with my customer login page on my site using both redix php cache + redis object cache.

If you visit the customer login page, first time you provide the username and password to login and click the login button, page just reloads itself. It will neither show you any error in case you provide any wrong login details nor it will take you to the dashboard in case you provide the right details.

So, you have to provide the details for the second time and then it will work as expected. I'm not sure what's causing this issue. Do you have any idea about how to fix it?
