The main domain is not passing the login session but Subdomain does

[StewardK]

I have installed the plugin but noticed that the main domain is not passing login session to the subdomain but the subdomain login session is passing smoothly. I checked all the settings are made sure there is difference in configuration

Am i getting something wrong?
