Just purchased Sweet-dessert theme CANNOT install says, " Cannot connect to Server" this is when uploading through wordpress das

Cannot install in wordpress dashboard, says repeatedly, “Cannot connect to server” have reinstalled wordpress, have not been able to install child theme either,

Check first if you try to install all pack zip or only theme.

Then speak with your host to rise limits php for upload and max time

Then you can also try to upload using ftp.

Good luck
