Currently, uBlock Origin extension blocks websites when detecting scan of open ports on the 127.0.0.1 (localhost) address. At the same time, the abovementioned port is used by some government and non-government information systems to operate NCALayer application.

In case of NCALayer connection error, make sure that uBlock Origin browser extension is disabled and that a website which you try to access is added into exclusions in the settings of uBlock Origin extension. 

To disable uBlock Origin for popular websites (Google Chrome, Opera, Mozilla) you need to open a homepage of the required website (for instance, pki.gov.kz, egov.kz, goszakup.gov.kz) and perform the following actions:

1) in the upper right corner click disabler icon (U).

2) click turn off icon.
