Working thread to coordinate the restart of Supernova.

## Datetime: TBD

## Configuration Checks

### Sentry | Validator | Archive Node Seed Addresses

`seeds = "ee5a4e4d21e3248f8efebbcb7889b434c4c48ba4@3.94.70.251:26656,2a3cd2768826aed5792593a2d6c8f6b28435a2a7@172.245.233.171:26656,ced855d1514b84adabe8590acd474487710ca259@167.235.79.123:26656" `  
_ **Note:** _ Seed node operators _ **only** _ should remove the seed address of their own seed. This means if you operate a seed node you will only have (2) seed addresses.

## Validator node:

- unconditional\_peer\_ids = “your\_sentry\_node\_id(s)”
- persistent\_peers = “your\_sentry”
- pex = “false”

## Sentry node:

- unconditional\_peer\_ids = “your\_validator\_node\_id”
- persistent\_peers = “your\_validator”
- private\_peer\_ids = “your\_validator\_node\_id”
- seeds = “seed\_nodes”
- pex = “true”

## Other

- Check supernovad binary version v0.0.4.
- Check the supernova.service.
- Check ufw status and ALLOW every connection to and from port 26656.
- Check the genesis.json hash.
- Check that the selected db backend is rocksdb.
- Check that your sentry, validator or seed full node is fully synced.
