Thank you very much for your prompt reply. But interestingly, the account
was not in-active even for one minute. While I log into dhis2 and then try
to got any other app (system settings, maintenance etc.) or even I reload
the dashboard page, 5 out of 10 times it provides this error.
Also in the chrome browser console I received following error.

Thanks & Regards,
