We noticed this in our custom embedded Linux device (at work), where when we didn't have the time sync with NTP turned on for boot (but rather a cron job at an interval further away from boot time) and that our RTC's coin cell was drained due to a small hardware bug, that at first when our API calls from the device were failing that we thought it was a hardware / software driver (WLAN) issue, but it fortunately turned out to be the innocuous issue of TLS failing due to the system clock being so off!
