Это и есть наша причина! Ссылка на решение от Веднора - SSLV3 enable

Solution Caution

These steps expose the security vulnerabilities with SSLv3. This issue is resolved in VMware View 6.2, available at VMware Downloads. For more information, see VMware Horizon 6 version 6.2 Release Notes.

The SSLv3 support can be enabled for these ports and services:

CIM Port 5989 Authd Service Port 902 Enabling support for SSLv3 on CIM Port 5989 in ESXi Create a backup copy of the /etc/sfcb/sfcb.cfg file.

Edit the /etc/sfcb/sfcb.cfg file to append the following line at the end of the file:

enableSSLv3: true

Note: If you have the line enableSSLv3: false in the file, change it to enableSSLv3: true

For Example:

cat /etc/sfcb/sfcb.cfg # Generated by sfcb-config.py. Do not modify this header. # VMware ESXi 6.0.0 build-3029758 # basicAuthLib: sfcBasicPAMAuthentication certificateAuthLib: sfcCertificateAuthentication cimXmlFdHardLimit: 1024 cimXmlFdSoftLimit: 512 . . . threadStackSize: 524288 useChunking: true sslCipherList: HIGH:!DES-CBC3-SHA!CAMELLIA128-SHA!CAMELLIA256-SHA enableSSLv3: true

Restart the SFCBD service with the command:

/etc/init.d/sfcbd-watchdog restart Enabling support for SSLv3 on Authd service 902 in ESXi Create a backup copy of the /etc/vmware/config file Edit the /etc/vmware/config file to append the following line at the end of the file:

vmauthd.ssl.noSSLv3 = "false"

Note: If you have the line vmauthd.ssl.noSSLv3 = "true" in the file, change it to vmauthd.ssl.noSSLv3 = "false"

For Example:

cat /etc/vmware/config libdir = "/usr/lib/VMware" authd.proxy.nfc = "vmware-hostd:ha-nfc" authd.proxy.nfcssl = "vmware-hostd:ha-nfcssl" authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl" authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc" authd.fullpath = "/sbin/authd" vmauthd.ssl.noSSLv3 = "false"
Restart the rhttpproxy service with the command:
/etc/init.d/rhttpproxy restart 

Additional Information For the related Veeam Knowledge Base article, see http://www.veeam.com/kb2063.

Follow these steps to enable SSLv3 protocol on hostd service for ESXi 6.0 U1b later.

By default SSLv3 is disabled. If you want to enable SSLv3, set the setting to empty by using the below command:

Login to ESXi through SSH. Run the following command to get a list of disabled protocols for hostd:

esxcli system settings advanced list -o /UserVars/VMAuthdDisabledProtocols

Path: /UserVars/VMAuthdDisabledProtocols Type: string Int Value: 0 Default Int Value: 0 Min Value: 0 Max Value: 0 String Value:sslv3 Default String Value: sslv3 Valid Characters: * Description: VMAuthd disabled protocols. Choices are sslv3, tlsv1, tlsv1.1, tlsv1.2. By default sslv3 is disabled. If no protocol is specified, all protocols are enabled.

If SSLv3 is disabled, To enable SSLv3 is run the following command:

esxcli system settings advanced set -o /UserVars/VMAuthdDisabledProtocols -s ""

Restart the rhttpproxy services by running the following command:

/etc/init.d/rhttpproxy restart

Run the following command to get a list of enabled protocols for hostd:

esxcli system settings advanced list -o /UserVars/VMAuthdDisabledProtocols

Path: /UserVars/VMAuthdDisabledProtocols Type: string Int Value: 0 Default Int Value: 0 Min Value: 0 Max Value: 0 String Value: Default String Value: sslv3 Valid Characters: \* Description: VMAuthd disabled protocols. Choices are sslv3, tlsv1, tlsv1.1, tlsv1.2. By default sslv3 is disabled. If no protocol is specified, all protocols are enabled.
