Simple Sitemap using default instead of website URL https://www.drupal.org/project/simple_sitemap/
I am using above module
abc.com/admin/config/search/simplesitemap

When I am generating sitemap via UI or drush simple_sitemap-generate command.
It is using
 &lt;url&gt;
  &lt;loc&gt;http://default/ja&lt;/loc&gt;
  &lt;xhtml:link rel=&quot;alternate&quot; hreflang=&quot;en&quot; href=&quot;http://default/ja&quot;/&gt;
  &lt;xhtml:link rel=&quot;alternate&quot; hreflang=&quot;ja&quot; href=&quot;http://default/ja&quot;/&gt;
  &lt;changefreq&gt;daily&lt;/changefreq&gt;
  &lt;priority&gt;1.0&lt;/priority&gt;
 &lt;/url&gt;

On my Website I am using only English language. Other languages are configured. But not using that.
How to remove those?
This happenes when generating the sitemap via CLI cron without --uri parameter. Either pass the Domain into the CLI
drush --uri=https://www.example.com simple-sitemap:generate

or use the web interface to generate the sitemap.
