Node status mysteriously at "Not synced"

After rebooting and relaunching Chia I went from synced status to “Not synced”.

I have 148 peer connections, port 8444 is open and manually port forwarded to the full node machine and looking at log file and “Last attempted proof” section of the GUI I can see that it is responding to challenges.

Also the difficulty and the peak height match the latest (as per chia explorer) so I am confused why the status is showing “Not Synced”.

Is there something I am missing? Like I mentioned I was fully synced and after reboot and relaunch I am seeing the “Not synced” status.
