Hi @@Sigmund Taubert

Please check this link: https://una.io/my-sites

1. Do you have a valid UNA License? You can check it in the link above or here: https://una.io/products-licenses
2. Have you registered your site URL in your UNA account and generated the Key and Secret? See: https://una.io/kands-manage
3. Have you entered your Key and Secret in your UNA installation? Please Go to Studio > Settings App > General.
4. Have you checked your Cron job? Have you set it correctly and is it running? When was the last cron jobs execution? To find out, please Go to Studio > Dashboard > Host Tools > Server audit (check under Site setup)
5. Have you read my post above? It might be the wrong site url in your header.inc file (the config file). Please Go to inc/header.inc on your server where UNA is installed and check if the BX_DOL_URL_ROOT parameter (your site url) was set correctly upon installation. if not, then change it accordingly to meet your domain setting whether you are using a https://www or non-www domain. Please make sure that your site url saved in your header.inc file matches the url associated with your key and secret in your UNA account. See: https://una.io/kands-manage
6. If needed you can even reset your license here: https://una.io/products-licenses, then access the Apps Market again. It will associate your license with your site again.

Hope I have helped you. Thanks
