Cookies problem

Hello,

I am using CodeIgniter-3.0.0 (same problem exists in older versions) + CodeIgniter-Authme (https://github.com/williamknauss/CodeIgniter-Authme) and I use CloudFlare, I have two internet providers, when I use first provider everything is working fine but when I use the second internet provider there is a problem which is random and frequent logouts when I log-in it is ok but sometimes when I move to another page I find myself not logged in also sometimes when I close the browser and visit the site again I find myself not logged in. Also a member in my site from another country emailed me with the same problem. I found such issues on the internet with users using Ci with CloudFlare but I didn't find a solution other than disabling the CloudFlare.

Any help???

Thanks
