You are not alone. I can't either and problems were reported by others at DBS IO groups

Bonjour, pour moi aussi impossible de se connecter au site D'Embroidery Allsorts, on me met que le site utilise un protocole qui n'est pas compatible.

Allsorts has been working for me. She closed it to revamp it but it is working and I think for the better. There is still someone spewing out bad vibes on the freebies and her site. She is re-running the FSL Pinecone numbers along with her updated letters of UC and LC....she now changes her designs at 8:00 a.m. Brisbane time so I know that is 5:00 p.m. EST. Today, now is the UC and LC 'M' and I believe number 7.

The site is still very slow at loading. Be patient, you will eventually get in.
