It’s not possible to connect to my host (InMotion Hosting) with Bootstrap Studio SFTP even if I use the exact same credentials and settings that work perfectly in other SFTP clients. The issue may be that Bootstrap Studio doesn’t allow the simultaneous use of the SSH key, key password, and login password, unlike other SFTP clients.
Thank you for the report! We are preparing an update for the SFTP upload functionality in our next release, which should fix these issues. Until then the only workaround is to use Filezilla or other clients to upload your site after exporting it from Bootstrap Studio.
