# Solve On-Premises 8.7: Hyphen in the hostname or domain of SOP server is missing

## Issue

If you use a hyphen in the **Hostname** and/or **DNS Domain** field of a URL, for example, SOP-VM, the hyphen will be cut off in the server's real FQDN in Solve On-Premises (SOP) version 8.8. ![Hostname details field](https://cdn.document360.io/098100b7-b9da-4bea-b4b9-017140ab863e/Images/Documentation/image-RCPJ0XXV.png)

          **Note**

          

This problem affects all current versions of SOP.

## Workaround

1. Secure Shell (SSH) into the SOP machine that has the hostname and/or DNS domain without the hyphen.
2. Run the following two commands to replace the hostname and DNS domain characters:

```
sudo sed -i '/HOST_NAME=$(SanitizeHostname $USER_HOST_NAME)/c\HOST_NAME=$USER_HOST_NAME' /opt/scripts/setup.sh
sudo sed -i '/DNS_DOMAIN=$(SanitizeHostname $USER_DNS_DOMAIN)/c\DNS_DOMAIN=$USER_DNS_DOMAIN' /opt/scripts/setup.sh
```
3. Reboot the machine.

The `ovf-env.xml`, located under `/opt/cdrom`, contains Solve environmental variables, such as hostname, DNS domain, and other network information.

1. Run the following command to verify that the hostname and DNS domain are saved with a hyphen.

```
grep hostname /opt/cdrom/ovf-env.xml
grep domain /opt/cdrom/ovf-env.xml
```

If the hostname and DNS domain are saved with a hyphen, the following response appears:

Property oe:key="guestinfo.hostname" oe:value="**SOP-VM**" Property oe:key="guestinfo.domain" oe:value="**my-test-domain.local**"

The SOP server runs the configuration and sets the correct hostname and/or DNS domain with the hyphen.
