Storagenode does not start (network connectivity problem )

It looks like my current Internet provider (AT&T) is blocking NTP in both directions allegedly to prevent Reflective DDOS attacks.

Had to reboot my system (due to StorJ storagenode docker container leaking memory and ending up allocating over 32GB of RAM!), but now the node does not want to come up anymore, because it fails its pre-flight check (log image attached).

Does anybody have any idea how to solve this problem?

Thank you
