Garmin Export Intermittent!

Hi My connection to garmin has always been 99% reliable - my activities always appearing in garmin connect as a “Zwift - Watopia” (Virtual Cycling) activity, etrc…

on 7th dec and 8th dec i had 2 rides that did not export to garmin so i removed and re-made the connection to garmin in my zwift profile…

on the 9th dec and 10th dec my rides again exported as expected to garmin…

then today (the 11th) again no export…

Seeing as this link up happens server to server and not directly from my PC (i assume)… how can I debug this and get it resolved so it is again reliable.
