Unable to access "Admin"

Complete beginner here. I had started building a website but took a week off. Yesterday I logged in and opened the site but when I click on the Admin button I get a message that says safari unable to open webiste because the server unexpectedly dropped the connection. Tried several times since but same response. Updated to latest version of Local before starting.

I have now been able to access my website build but I can not update any new work. same message.

On trying to add text using the text widget I get the message “Unknown error. Failed to load the form. Please check your internet connection, contact your web site administrator, or try again later.”
