Manually Verify Domain (HTTP Server) by uploading two txt files in /.well_known/acme_challenge/

Hi, I am trying to set up ssl for my domain ( with sssforfree service on a free hosting plan.
The procedure requires to verify my site before issuing the key and certificate to upload then in the ssltss area in cpanel.
when I try to upload such txt files (via ftp - mozzilla, or with file manager) the files aren’t uploaded in the directory (/.well_known/acme_challenge).
I do not know how to verify domain adding a txt record to dns, and ftp verification does not work either.
can someone point me in the right direction?

Thank you for your kind reply.


I’m sorry, but uses Let’s Encrypt, which is not supported with us unfortunately.

thank you for your reply. I will look if it is for me possible to purchase a ssl cert directly from you then so I’ll also get your help for installation.
