# Troubleshooting

This page will contain problems with their possible solutions.

### Error: post failed: Post "<http://localhost:26657/>": dial tcp \[::1]:26657: connect: connection refused

Can't link the wallet to post the broadcast. Make sure your wallet is active in the CLI and that the right wallet was added to the command.\
To create a CLI wallet see [Creating a CLI wallet](/shentu-chain/validators/creating-a-cli-wallet.md)<br>

### Shentud not posting upon startup (After snapshot implementation)

We've seen that it can take up to 30 minutes before shentud posts after implementing a snapshot. For this all you can do is being patient.<br>

### High disk usage while running the Validator

This could be improved by modifying the pruning settings. These can be found in app.toml.

```
pruning = "custom"
pruning-keep-recent = "100"
pruning-keep-every = "0"
pruning-interval = "10"
```
