Inactivity

If you have not been doing anything on the page for a set length of time (often 10-30 minutes), the server times out your session. Inactivity timers were created for security reasons and to help increase the overall speed of the web page. For example, if you were browsing the page and got up to leave, you'd need to log in again and create a new session when you returned.

Can I increase the length of time a session expires?

A website session duration is measured and managed on the server, not on your computer. Therefore, you cannot modify the remaining time of a web session.

Unstable Internet connection or disconnects

If your Internet connection is unstable, periodically disconnecting and reconnecting, it can cause a website session to expire. When the Internet connection is lost the website connection can be terminated, resulting in a session expired message if you try to access any page after the Internet reconnects.

Date or time not correct

Make sure the date and time are properly set on your computer. An incorrect date or time on your computer can cause reconciliation issues between the website and your computer, and can cause the session to expire.

Cookies

If you're browsing anonymously or your Internet browser does not have cookies enabled, it causes many sessions to fail. Make sure Internet cookies are enabled in your browser.

Firewall or proxy

If you're connecting to the Internet behind a firewall or through a proxy, that might restrict or prohibit the session from being established. If a session is not established, you can get a session expired message immediately or very shortly after connecting to or logging in to a website.

Virus or malware

If your computer is infected with a virus or malware, it can cause problems with establishing or keeping an active session on a website. Make sure you have an antivirus program installed, fully updated, and run a scan to remove any viruses or malware found on the computer.

Other site related issue

If the issue only occurs on a certain site and no other website. Contact the company or webmaster to verify the problem is not on their end.
