Server says 'Starting' then randomly stops

So my friends and i had this sky factory 3 server we used to play on a year ago with aternos, and it worked fine. Recently, we decided to start it up again. We each had a copy of the world and we each sat through the 40 minute wait time in the queue. Finally, one by one, the server started saying 'starting' and after about 7 minutes it just randomly switch to 'stopping' then to 'offline'. There wasnt any error that i could see in the console or log and it stopped without any warning. The console got cleared immediately afterwards. We have tried this on multiple occasions and each time this exact thing happens. If you could help we would really appreciate it

EDIT: We realised that we are idiots xD We needed to type /fml confirm in the log?
Anyway, its all good.
