No required ssl certificate was sent
How to solve ssl certificate error.
Good day, everyone. I configured a http listener on the load balancer (frontend http 80 to backend server (ecs) port 80) and it works perfectly. And here’s the issue: I’ve successfully uploaded SSL certificates (both CA and Server certificates), and I’m attempting to set up https listener on my server load balancer on frontend https 443 to backend server (ecs) port 80, but I’m getting this error 400. Unacceptable Request There was no requirement for an SSL certificate to be submitted. nginx nginx nginx ngin I’ve already double-checked my certificate using https://www.sslshopper.com/ssl-checker.html and https://dev.ssllabs.com/ssltest/index.html, and my SSL certificate is flawless, with an overall rating of ‘A’. Someone, please, tell me why this is happening.
Hello, I believe you are not properly configuring Nginx to submit the SSL certificate that you have uploaded. I configured a http listener on the load balancer (frontend http 80 to backend server (ecs) port 80) and it works perfectly. SSL traffic (HTTPS) listens on port 443, not 80, and I’m not sure if this is the issue. HTTP traffic is routed via port 80.
How to enable client certificate authentication for https
Mutual TLS is one of the pillars of Zero Trust Networking (known as mTLS). To put it another way, each client must present a certificate in order to communicate with the server. By replacing credentials with certificates, we can increase security (especially with short-lived certificates like the ones we provide) while also simplifying implementation (by eliminating the need for API key/credential management).
We’ll put it all together in this article by creating a sample implementation. A basic Python appserver will be used as the example implementation, with a Nginx reverse proxy in front of it. All connections without a valid certificate will be rejected by Nginx, and the appserver will compare the certificate to a whitelist of devices that are allowed to communicate with the server.
Now we’ll look at Nginx. For the appserver that we will discuss later, we use Nginx as a reverse proxy. We do it for a variety of reasons. The first reason is that Nginx has been through the ringer and performs the initial screening. The request will not be forwarded to the appserver if the client does not present a valid certificate, for example. As a result, this provides a useful safeguard against potential bugs in the appserver code.
Tutorial: client certificate authentication
I downloaded a certificate and installed it on my iOS device using Safari. However, when I run my app and query whether the site requires a client certificate, the message “No required SSL certificate was sent” appears. How do I locate and send the client certificate to the server?
SecPKCS12Import can be used to import a digital identity. There are many examples of how to use that routine, so I’ll skip ahead to the difficult part, which is obtaining the PKCS#12 data you want to import. This is a difficult task that is highly dependent on the environment in which your app runs.
Ideally, administrators would be able to use a configuration profile to push a digital identity to a particular keychain access group. This is a frequently requested feature, but there is no indication that it will be introduced. If you’d like to join the choir, please submit an enhancement request with details about your needs. You’ll have to come up with a different way to get your PKCS#12 data if there isn’t such a feature. There are a few options, but in managed environments, I believe Kerberos SSO is the best choice. You can take one of two approaches to this: Aside from that, there are a number of less-than-ideal options. Many people, for example, use managed app configuration for this , despite the fact that we explicitly warned people not to use it for passwords when we first released it. 1st Extending Your Apps for Enterprise and Education Use (WWDC 2013 Session 301). Regarding your other inquiries: Is there a step-by-step guide on how to… implement client certificate-based authentication in our app? Depending on the networking API you’re using, you’ll have to do it in a different way. If you’re using NSURLSession (or something similar),

Note that the version of OpenSSL used (1.0.1e) is quite old and contains a number of known bugs, some of which are quite obscure (see #215 for an example). Please try reproducing the issue with a recent version of OpenSSL (and without any third-party modules to ensure they don’t interfere). If you are able to replicate the problem, please provide the following information:
Unfortunately, there are no interceptions between “client sent no necessary SSL certificate” errors in the debug log provided (and source port is known, so we can detect a connection at the network level) and the packet dump provided:
