I've changed the main domain on your account from csierrae1815 to hotel.helioho.st and added the api subdomain.
Please note that it may take up to 2 hours for your new domain to fully work. If after a full 2 hours it doesn't work on your side, please make sure you clear your web browser cache: https://wiki.helionet.org/Clear_Your_Cache
Once it has been a full 2 hours, the httpdocs folder in your account will relate to the new hotel main domain. If you still run into issues connecting your git repo, please share a screenshot of the settings you're trying in Plesk's 'Create repository' window, so we can investigate this further for you.
Please note there is a risk of data loss when main domains are changed, so I made a full backup for you before I made the changes, in case you need any files from the old maindomain. You can download the backup here: https://heliohost.org/backup
If you're not sure how to extract the backup files, please follow our how-to guide here: https://wiki.helionet.org/Account_Backups
If you're using Laravel, we recommend using the Plesk Laravel Toolkit, shown directly on the left side menu inside Plesk. We have some more guidance on Laravel on our technical documentation Wiki page at: https://wiki.helionet.org/Laravel that should be useful for you.
