# Troubleshooting and security

> What the messages mean, and how Condense protects what you store.

## Messages and what to do

> [accordion] The alias is already used
>
> Condense tells you that a connection with this alias already exists. Choose a different alias, or re-configure the existing connection instead.

> [accordion] The certificate or key cannot be read
>
> Condense tells you it cannot read the certificate or private key. Check that the content starts and ends with the usual `BEGIN` and `END` lines and that nothing was cut off when you pasted it.

> [accordion] The broker rejects the credentials
>
> The test reports that authentication failed and shows the response from the broker. Check the username, password, token or keys, and the authentication method you chose.

> [accordion] The broker cannot be reached
>
> The test reports that the broker cannot be reached. Check the address and port, and make sure your firewall or VPC allows Condense to reach the broker.

> [accordion] A file is too large
>
> Condense refuses a file over 12 MB and says so under the field. Use a smaller file, or paste the content with the Paste Content switch.

## How your credentials are protected

* Secret fields are masked as you type.
* Secrets are encrypted before they are stored.
* Secrets are never written to logs.
* Only you can see your connections.
