# Some things to try

## Balance

Run the `catchup.sh` script first. If you're caught up but your validator is delinquent, then check your `validator-keypair.json` balance.

- Check the Identity Account balance...you need to pay fees out of this account to vote on transactions.

:::CodeblockTabs
CLI

```linux
xandeum balance validator-keypair.json
```

## Stake

If you're online but not in the `xandeum validators` list, Check if there is any tokens staked to your vote account. If not, follow up with Labs to get you staked.

:::CodeblockTabs
CLI

```linux
xandeum stakes ~/vote-keypair.json
```
:::

:::hint{type="info"}
If it shows a stake account, but has the phrase `Stake account is undelegated` then it means you were delinquint at some point and your stake was removed to lower the delinquincy level. See examples below.

## Connections

Restart your validator and watch for the TCP connections to suceed:

:::CodeblockTabs
CLI

```linux
sudo systemctl restart xand.service &&
tail -f ~/xand-validator.log | grep --color=always -B 10 -A 50 "Checking that tcp ports"
```
:::

![](https://api.archbee.com/api/optimize/ePevXmvzgG-7aqJ72Gpg_/56jMMbbVixqAyEt8RMziI_image.png "Correct ports are reachable")

:::hint{type="info"}
Look for the ports to be "reachable"

- tcp/8899
- tcp/8900
- tcp/8000

This will tell you a lot about your router environment. If it fails the first time, it will try again. UDP is important too, but usually the first indicator of trouble is TCP.
