I am running into the POODLE Chrome issue when accessing my https://localhost:9443/vsphere-client
My Virgo server is up and running. But when I try to launch on Chrome, I get this error:
A secure connection cannot be established because this site uses an unsupported protocol.
Error code: ERR_SSL_VERSION_OR_CIPHER_MISMATCH
Can you please suggest a resolution to this issue.
Please always add version information to your questions, I cannot guess what you are using (Web Client, Chrome, etc.)...
Also err_ssl_version_or_cipher_mismatch doesn't mean it's the poodle problem.
We have seen this error with the latest Chrome version with SDK 5.5.x, it must be a side effect of some internal change they made. It only happens for localhost, i.e. a dev setup.
The work-arounds I know of are:
- Use an older Chrome version just for your local plugin development.
- Use Firefox
- Use SDK 6.0 where this problem doesn't exist.
We don't have a solution for the latest Chrome and SDK 5.5.x but if someone has found one please share it here.
I assume it has to do with an invalid certificate.
Thanks will try them out.
Quick question on SDK 6.0 - which vcenters will this be compatible with? Do we have to upgrade and install everything to 6.0. I am not clear on that, can you please explain.
As always the Web Client and its SDK is compatible with the current release and the previous one, so SDK 6.0 is compatible with vCenter 6.0 and 5.5.
To use Web Client 6.0 you don't need to install or upgrade to vCenter 6.0 but you need the new 6.0 service controller.
See this doc "Mixed-Version Transitional Environments in vCenter Server for Windows Upgrades": vSphere 6.0 Documentation Center
Will you be providing a patch for 5.5 SDK to work with Chrome? We are committed to release our product for 5.5 SDK only, and this would be a blocker. Please let us know the plan on fixing this issue.
Chrome does an automatic upgrade and I didn't find any easy way to downgrade or ask chrome to use an older version.
Still that doesn't solve the problem unless vmware comes up with a patch.
Laurent, I see this error in fire fox too.
Secure Connection Failed
An error occurred during a connection to localhost:9443. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)

Please.... Chrome and Firefox don't work!!!! I need help. How can we develop! I have a release, and my development is completely halted!
It is just not localhost, I can't even use the system's ip to go. Please WE NEED A PATCH!
The Answer is Here

*POST FROM SPICEWORKS*
For Chrome v40: Open chrome://flags Look for "Minimum SSL/TLS version supported." Choose SSLv3 Click on "Relaunch now" button Open your https page again You will be redirected to a "Your connection is not private" page. If you do not worry about this security issue click on the "Advanced" link. Finally click on "Proceed to (unsafe)". Solved.
I am Using Chrome v42, and this still works
The Google is not strong in you - this took me 3 mins to find the answer - and then another 15 mins to do the right thing and register and post here - as it seemed you guys were getting nowhere.
Good Luck and Enjoy
This is the correct way to do it. The certificate must be replaced because DSA certificates are no longer supported.
Please, don't use the workarounds further above (e.g. tampering with the "Minimum SSL/TLS version supported" flag in Chrome) because they don't really solve the problem and they will stop working in the future when such workarounds get disabled in the browsers.
So, to create a Virgo server certificate similar to the original one, but using an RSA algorithm, do this:
keytool -genkey -alias s2dmk -dname "CN=SpringSource dm Kernel, OU=dm Server Team, O=SpringSource" -keyalg RSA -keystore keystore -keypass changeit -storepass changeit
Then replace file [VIRGO_ROOT]/configuration/keystore with the file you generated above. If you wish, you may back up the original 'keystore' file before overwriting it with the new one.
If necessary, you can also modify the HTTPS connector in file [VIRGO_ROOT]/configuration/tomcat-server.xml. Replace attribute:
Also, replace the 'ciphers' attribute with:
