Firefox For Mac Could Not Verify This Certificate Because The Issuer Is Unknown
Under a normal HTTP connection, the browser will tell the server which domain it wishes to connect in what is known as the host header. However, when a HTTPS connection is made, the handshake means the browser requests a certificate from the server before it presents the host header. As a result, the server does not have the information required to decide which certificate to send and will often present the wrong certificate. 
Certificate installed / referenced on the server is a self signed certificate: A self signed certificate will have the same issued to and issued. Therefore, this is not a Thawte issued certificate. Even Chrome could not open Google.com. After a while I noticed that my time was off, and the date was set to 3 years ago. Reader for mac sony e-reader store. Updated to my local time zone, entered the proper date and time, and *drum roll* all my browsers were at peace.
I have had to de-install Avast Free version under Mac os 10.12.5 because I could not reach a heap of websites that I normally use. The firefox beta for mac with roku support phone number. The problem has already been described on this thread. I am using Firefox 54.
I created a self-signed CA cert using openssl, and imported it into Firefox, but when I select it in the Certificate Manager under “Your Certificates” and click “View”, I see the message “Could not verify this certificate because the issuer is not trusted.” When I visit the site that I set up with an SSL cert signed by that same self-signed CA cert, I get an untrusted connection warning with the following technical details: “staging.cakemade.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is not trusted. (Error code: sec_error_untrusted_issuer)” When I view the site certificate, it correctly identifies the issuer as the CA cert that I imported, but also displays the message “Could not verify this certificate because the issuer is not trusted.” I am using Firefox Aurora, and apply updates daily. I am using the default settings for OCSP. What do I need to do to get Firefox to trust the CA cert that I imported?

After I configured my apache with the server cert, key and intermediate cert and importing the root-CA to firefox 24 I received the following error when I browse to the website: > > Could not verify this certificate because it was signed using a > signature algoritm that was disabled because that algorithm is not > secure > > > I assume the reason for this error message is that I see 'Certificate Signatore Algorithm' is 'PKCS #1 MD5 With RSA Encryption' for the Intermediate Certificate and Server Certificate.

This requires administrative access. C) This will launch the 'System Properties' dialog, with the 'Advanced' tab selected. From this tab, click the 'Environment Variables' button d) This will launch the 'Environment Variables' dialog. Under the 'User variables for ', there will likely be a variable called 'PATH' already.
Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system. In fact, one misplaced comma can prevent your PC from booting entirely! Because of this risk, we highly recommend using a trusted registry cleaner such as (Developed by Microsoft Gold Certified Partner) to scan and repair any Error sec_error_unknown_issuer-related registry problems. Using a automates the process of finding invalid registry entries, missing file references (like the one causing your sec_error_unknown_issuer error), and broken links within the registry.
T-Bird, of course, complained about a cert that it couldn't verify. When I click on 'Examine Certificate.' The dialog box tells me that it can't verify it because it doesn't know who issued it.
Actually curl uses this file only to make its own life easier so that curl doesn't have to distribute a set of trusted CA certificates, it just piggy-backs with something OpenSSL has. Free audio recorder for mac. Since this approach is OpenSSL-specific there is a procedure for adding own CA root-certificates into your system. When a new CA-root needs to be installed the mechanism is not to copy the certificate into this big file. How to actually do it, we'll get into that later.
