-Please be patient once you start the node and observe the logs. Dumps come without DHT caches, so it will take your node some time to find other nodes and then sync with them. Depending on the age of the snapshot, your node might take from a few hours to several days to catch up with the network. This is normal.

If so, ensure that the IP address defined in the `addrs[0].ip` field of the `/var/ton-work/db/config.json` file corresponds to the real public IP of the machine. Note that the value of this field is specified as a signed INT. The `ip2dec` and `dec2ip` scripts located in [ton-tools/node](https://github.com/sonofmom/ton-tools/tree/master/node) can be used to perform conversions.
