With the internet speed shown on the graph below, does anyone know how long it can take to synchronise LND with the graph? After I had to close a couple of exhausted channels and performed the corresponding manoeuvres, I had to stop dependent apps, uninstall, reinstall and basically configure LND-app three hours ago or so.
Please let me know your suggestion.
Hey guys, It has been synchronised! It took approximately four hours 
It was not necessary to restart the server or any other manoeuvre.
The initial sync can take some time, as you’ve discovered. You’ll find it sometimes also takes a while after something has happened… like a sudden stop, upgrade etc. In those cases, if it’s taking more than several minutes then it might be stuck. Your instinct to restart is a good one in this case… but just restart the LND service itself, rather than the whole server so that you can keep Bitcoin Core running.
