This typically occurs when there are multiple Tk20 sessions opened, and it causes time-out issues.
This happens when the user has opened the application in multiple browser tabs/windows without signing out the previous session. It generally leads to OOPs/time out error. Please follow the below steps to clear the "OOPs" error.
· Close all current internet windows
· Launch one window to access Tk20
· Login to Tk20
· Navigate to the silhouette at the top-right corn of the page that says, "Hi Name"
· Click on the drop-down, then click "Sign Out"
· Proceed to clear the browsing data and history using the steps for the browser being used.
· Closed ALL internet windows
· Reopen only one window to access Tk20
· Login
