To turn off wildcard subdomains in Forge, you can follow these steps:
- Log in to your Forge account and navigate to the server that hosts your site.
- Click on the "Sites" tab and select the site you want to modify.
- Scroll down to the "Domains" section and click on the "Edit" button.
- Remove the wildcard subdomain entry (e.g. "*.example.com") from the list of domains.
- Add the subdomain you want to use (e.g. "subdomain.example.com") to the list of domains.
- Save the changes.
You shouldn't encounter any issues when turning off wildcard subdomains, as long as you update your DNS records accordingly. You may need to remove any A records that point to the wildcard subdomain and add a new A record for the subdomain you want to use. You may also need to update your SSL certificate to include the new subdomain.
Here's an example of how to add a new A record for the subdomain using the command line:
$ sudo nano /etc/hosts
Add the following line to the file:
127.0.0.1 subdomain.example.com
Save the file and exit. This will create a new A record for the subdomain that points to the local IP address.
You can then update your DNS records to point to the new A record. Once the DNS changes have propagated, you should be able to access the subdomain using the new domain name.
