enable TLSv1.2 for your servers


(Mark „Tsu“ Mark (D)) #1

If the old TLS versions 1.0 and 1.1 are disabled on a Windows PC running the client, Zwift will not start. Instead, an error message appears that “0 bytes have been read from the transport stream.” This is because TLSv1.2 is not enabled on server-side.

Please enable TLSv1.2 on your servers (or TLS terminators or what-have-you).
