![]() Lent specifically reminds us that we are sinners who are in need of Jesus's sacrifice. In the same way advent prepares us to celebrate the birth of Jesus at Christmas by helping us take time to think about the significance of that event before the day comes, Lent prepares us to honor the sacrifice and death of Jesus. It was instituted as a reminder to repent of sin and meditate on the sacrifice of Jesus in the weeks leading up to Easter. Depending on the year, it can begin in February or March, but it always ends on Easter. Lent is a period of forty days (excluding Sundays). So, what is Lent? Should all Christians observe it? What is the purpose of it? Let's explore each of these questions together. Perhaps you have heard it talked about in your church or on social media. There are many denominations that do not observe Ash Wednesday but do take part in the Lent season. Ash Wednesday is traditionally observed by Catholics but is also observed by some other denominations as well. The crosses are drawn in ash and signal the beginning of the Lent season, which begins today, Ash Wednesday. ![]() Figuring out exactly why this occuring requires more information about the context these requests are being sent from, but hopefully that’s a good starting point.As you go about your day today, you may see people with small black crosses on their foreheads. It’s strange, then, that the application typically works for everyone and has only broken down in these isolated cases. This can be confirmed using the standard SSLLabs toolset and opening the panel labelled Certificate #2: RSA 2048 bits (SHA1withRSA) No SNI: The OpenSSL behaviour suggests that the site totally fails to work without an SNI extension. Looking back at the packet capture for the original exchange, the one triggered by the Syrinscape Creator software, I can see that Syrinscape (or its underlying HTTP framework) didn’t send an SNI extension in its ‘Client Hello’ TLS handshake. Openssl s_client -connect :443 -tls1_2 -servername I observe the correct behaviour if I add an SNI extension in OpenSSL, as in: The certificate is providing under these conditions is the same one found by default for some letsencrypt configs as located here: I observe this same behaviour if I connect to the server directly using openssl without an SNI extension: It receives a certificate in which subject=/CN=* and issuer=/CN=* instead of the legitimate certificate. If I use Wireshark to watch traffic, I see the start of a TLSv1 handshake between my client (presumably the Creator server) and in which my client rejects the handshake because the certificate is invalid. The content of that error with “From callback” removed is an error others have encountered verbatim in C#/Mono contexts and in Unity projects: The error I receive is “From callback, Error getting response stream (Write: The authentication or decryption has failed.): SendFailure”. They are provided by the same password manager I use to log in at and I have compared the values explicitly. My username and password are definitely correct. The rest of this post is technical mumbo-jumbo. I’ve taken some steps to debug the problem myself which I hope are helpful as it seems others have also encountered this behaviour. I’m having the same login issues as detailed in this thread and this thread.
