How to unjail the validator

Check the reason for jailing:

cored q slashing signing-infos will show us the status of all validators, where you can see the jailed one and check the reason.
If the validator is jailed for being offline, there is reasonable jailed_until time, and tombstoned is set to false. You can unjail it.
If the validator is jailed for double signing, it means there are two replicas with the same priv_validator_key.json file. In this case, one will be tombstoned withjailed_until 9999-12-31T23:59:59Z, and tombstoned is set to true. It means that there is no way to unjail the tombstoned validator Another replica is jailed with reasonable jailed_until time and tombstoned is set to false. You can unjail it.

If the validator is jailed but not tombstoned, the next steps will unjail it:

Fix the reason for jailing.
Send unjail transaction on behalf of the stalker account who owns the validator:

cored tx slashing unjail --from {VALIDATOR_ONWER_ACCOUNT}
# where VALIDATOR_ONWER_ACCOUNT - Name or address of the account to sign the transaction

(Optional) Check the validator's state If your validator is up and running, you can check its state by sending the next command:
```
cored status --node={YOUR_RPC_ADDRESS}
# where YOUR_RPC_ADDRESS is your validator public http address
```
