[ovirt-users] SPICE HTML5 Browser Clinet does not work

Hi everyone, Today I have updated oVirt 3.5 to GA from RC5. And I have tried SPICE HTML5 Browser Clinet, but console screen is 'blank'. Before updating to GA, My oVirt 3.5 could display console screen correctly. Browser is the Firefox 31 running on Windows 7. Toggle messages output shows: Connected to wss://ovirt.rxc05271.com: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 Channel type 9 unknown.
