1. usr/click/bin/ha_domain/domain.c

(Correct the syntax error in the function load_sync_config_cli_real() to ensure that synconfig runs properly.)

2. usr/click/bin/sync/remote

(Make a duplicate of the certificate before running sync script (which cause the certificate to be deleted). And overwrite the certificate after sync is complete.)
The first idea is to :

- Check on clear_webui_config() -> which will be run during CLI command clear config secondary / primary

- clear_webui_config (called on sys_tool.c, the body of this function is on webui.c)

- clear_webui_config will call -> webui_ssl_clear_cert(), 

  but if we just remove this it might affect the system architecture

Testing using two vAPVs which have the HA environment:

1. Import WebUI Certificate on both devices

   (System > Access Control > WebUI Certificate)

2. Save memory on both devices.

3. Perform reboot on the first device (primary).

   (System > System Management > System Shutdown/Reboot > Reboot)

4. Check the primary APV for the WebUI Certificate 

   (Before the provided, solution the certificate will revert to default)
