Hello Mrg,

1.) Close the UFile session by exiting the UFile page ie close the browser and login back in.  The data should not be lost and all entries should be restored (except the last interview page).  It may be due to a split second disconnect of the  DBase to web server interface page and can be caused by network latency, internet disruptions or other internet issues.  

2.) Check Firewall / Antivirus settings

3.) Also reported when a user is behind a PROXY or other Web service which changes the users IP address during the session in UFILE. Eg. Using a corporate network. Try on a connection outside a VPN (Virtual Private Network).

4.) Clear the cache.

5.) Switch browsers.  Eg. From Chrome to EDGE

6.) Check for browser extensions eg. Crypto wallet / Cisco Webex

>>Chrome >> Settings >> Manage extensions.

7.) Reboot the modem to change the IP address.

7.) Try to open your account from a different location ie different IP address: home or office (if the modem reboot did not change the IP address).
