[LoneWalkerWolf]

Describe the bug
Whenever I run the ./start-sync.sh command, I get the below error.

HTTPSConnectionPool(host='api6.ipify.org', port=443): Max retries exceeded with url: /?format=json (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f7473106160>: Failed to establish a new connection: [Errno 101] Network is unreachable'))

To Reproduce

1. Go to directory.
2. Run ./start-sync.sh
3. See error.

Expected behavior
It connects and gets my IPV4 and IPV6 address?
