ISSUE

I have teleport setup with IP whitelisting in security group, I have used the dns challenge way to gain the certificate and have disabled acme, Behind this I have jenkins and Grafana with JWT setup, with initial setup it works and I login with the Teleport users to both Jenkins and Grafana, but What i noticed is after some time like and 1-2 hr , when i retry it takes long time for grafana and jenkins to load and when they load they shows there default login page.

Then As soon as I remove IP whitelisting, it again start working fine but when i again whitelist IP it does same.
