As much as I hate to share this, our customers are all being forced to switch platforms due to the inability to resolve this issue. We have dealt with some incredibly complex security-related issues as a result of some vendors moving to more secure stances and others lagging behind, and this is the first for which we haven’t been able to engineer a viable solution. The issue seems to be related to certificate mismatches or unverifiable or untrusted certificates in the mix between AWS, CC, and our various systems and browsers. We just can’t figure out how to make the latter trust what is being presented from AWS and CC. We’ve agreed with our customers that we have all burned too many resources to continue seeking a solution that includes CC so another platform for them is our path forward at this point. Good luck everyone! I really hate we weren’t able to find another solution to this one! ... View more

The strangest part is that the images load without trouble in modern Edge and Chrome browsers which doesn't support the idea that RC4 ciphers are in use, and the issue is that IE11 and Office products are misinterpreting the ciphers and unable to display the content. It is very possible that the main issue is simply that many users are using insecure/antiquated software products that are incapable of decrypting the content being presented to them.  I am still digging into this to determine if we can find a secure way to get these images to display within older Outlook versions.  ...

This issue is related to TLS RC4 security ciphers still in use on Constant Contact servers. If you grab one of the images from your newsletter and drop it in Internet Explorer you will receive the following notice: This page can’t be displayed Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://files.constantcontact.com again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator. This link explains the cipher a bit more: https://support.microsoft.com/en-us/topic/rc4-cipher-is-no-longer-supported-in-internet-explorer-11-or-microsoft-edge-f8687bc1-1f88-9abe-5c81-b00c26290f36   Unfortunately, turning on TLS 1.0, 1.1, and 1.2 doesn't make a difference. Constant Contact needs to work on using modern security ciphers to resolve this issue permanently for everyone. ... View more
