Figure 1. Knox Gateway UI: Incorrect username or password

Open a terminal session.
SSH into the Knox Gateway host by entering the following command:
```
ssh [***KNOX-USERNAME***]@[***KNOX-HOST***].[***DOMAIN***].site
```
Replace KNOX-HOST.domain.site with the Fully-Qualified Domain Name (FQDN) of your Knox Gateway host.
For example:
```
ssh john@abc-1.example.com
```
Enter the password that you used on the Knox Gateway web UI.
If you are able to log in using these credentials, then you should be able to log into the Knox Gateway UI.
