/* MessageId: TA_E_INET_TLS Message code (in Hex): 0x24 Message code (in Decimal): 36
MessageText:
The secure connection to the activation servers failed due to a TLS or certificate error. This is most often caused by MITM (man-in-the-middle) attempts on corporate networks or, if on Unix operating systems (macOS, Linux, BSD, etc.), it's caused by out-of-date or missing "CA certificates". This means either keeping your system itself up-to-date, or manually updating the CA certs.

There's not really enough information to help, other than to say it's likely use-error. Most likely MITM of communication to/from wyDay servers. And they didn't correctly setup the MITM certificates.
