RPi has no RTC chip. If network does not provide NTP correctly dateTime starts from GCC release date. If this happens system dateTime is before start date for TLS certificate in Kodi repository and (on your system) certifcate not valid so Kodi cannot connect to repo.
Something is wrong with NTP process in your environment. We cannot see problem from Kodi log, need system log.
