Thank you to Support team for helping me solve the issue. For anyone else with this problem here is the fix.
Its a bug with at least up to 1.27.1. developer said they will fix in future.
supposedly nature of bug is if you don’t have ntp servers listed, show up with these javascript errors in developer console of chrome.
Fix is factory reset, then reconfigure device. upon the factory reset and turning everything back on. Everything else works as intended. Except after upgrading from 1.24 -> 1.27, no longer can get into router from wan side https. not sure why. Everything else worked including upgrading and syncing time with browser now. 😉
