Ssl Error No Cypher Overlap Sonicwall
Note that the cipher suite negotiated by Firefox and the ones shown in the TestSSLServer output are not those offered by Google Chrome. You are getting TLS 1.2 which is good.It appears that no ECDHE cipher suites are being offered, and none of the older RSA key exchange ones.Try adding at least (presuming you have no ECDSA certificate) TLSECDHERSAWITHAES128GCMSHA256 to the service cipher suite set.As long as contemporary browsers are being used (i.e., current Chrome, Firefox, Safari 10, Android 5+, iOS 9+, Windows 10 IE11/Edge, and not anything older), the only cipher suites needed (and the best ones to use) are the TLSECDHE(ECDSA RSA)WITHAES(128 256)GCMSHA(256 384). I don't think you can get the CHACHA20 suites using standard Java 8. If you have to support Windows 7/Server 2008/Server 2012 clients you will also need TLSDHE(ECDSA RSA)WITHAES(128 256)GCMSHA(256 384). No need to offer any other cipher suites unless obsolete clients must be supported.Note that ECDSA cipher suites are not used in the absence of an ECDSA certificate.Also, until the self-signed certificate is replaced with one issued by a commonly trusted CA, you will likely get some browser warnings. On the face of it, the TLS service is either not providing a suitable TLS protocol version or there are no cipher suites in the intersect between client and service.
The TLS service should minimally support TLS 1.0, and ideally TLS 1.2.What version of Java is in use? Have the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy files been installed? What type of TLS server certificate is in use?One way to inspect a TLS service is to use. Note that the cipher suite negotiated by Firefox and the ones shown in the TestSSLServer output are not those offered by Google Chrome.
May 27, 2019 I can not get to certain sites including google.com, facebook, and several others. Tried several solutions suggested regarding resetting some of the configuration settings 'security.tsl.xxx' in. Welcome to our community. You can write to our Sonicwall support team using the email address ITHelp@SonicWALL.com. Let us know if you have any further queries. None of these workarounds — absolutely.NONE. of them — works with FF 56. Looks like I’m stuck forever with “sslerrornocypheroverlap” if I want to keep using FF, particularly whenever I try to log into Amazon.com. Utterly absurd.

Have you ever encountered an issue whereby you used to connect to a site flawlessly with Firefox; but suddenly got blocked for no apparent reason? Firefox informs you that “Secure Connection Failed” and proceeds to give error code Error Code: sslerrornocypheroverlap.
It is quite weird for something that has been working just fine to suddenly stop working; yet no other external or internal changes were made to the system. The above error is a common occurrence in Windows XP computers but has also been experienced in later Windows versions.Users of Windows XP Service Pack 2 and Service Pack 3 are encouraged to update their Firefox browsers to Firefox24. It can be downloaded at. For later Windows users, just upgrade to the latest available Firefox version. Please contact the website owners to inform them of this problem.
Fix code sslerrornocypheroverlap errorNow the following steps will assist you in resolving the problem. Check to see if SSL3 and TLS1 are enabled. To do this, open Firefox and follow the prompts at.
Open a new tab and type about:config in the address bar. If you see any ssl or TLS written in bold, right click on it and select “ Reset”. It will revert to its default setting.If you are not up to all the techie stuff, here is another alternative (Firefox has restricted use of RC4 cipher);. Open a different browser, for example Opera or Google Chrome. Now click on “Internal Settings”. Take note of the “Enable RC4-Only Cipher Suite Support” checkbox and then ensure that it is disabled.NOTE: While the above method works well, it is recommended that users do these changes under supervision or advice from a computer expert.

Wrongly adjusting these settings presents a security risk for both.
