Hello, i am using ovirt 4.5.4-1.el9 standalone on Rocky Linux and have some struggle with vnc connection. I ve engine.mydomain.de which contains the ovirt-engine. I installed third party certificate successfully. So when i call engine.mydomain.de/ovirt-engine or node1.mydomain.de:9090 the browser tell me that connection is secured. My first host is node1.mydomain.de, which has currently one VM up. On Linux Client (Rocky Linux 9.2) 1. When i run "remote-viewer --debug /home/user1/Downloads/console.vv --gtk-vnc-debug" everything works fine. RemoteViewer opens and i can see the console of my vm 2. When i try to open the console.vv directly via remoteViewer from enngine-portal i get feedback from remoteViewer: "The certificate is not trusted" 3. When i try to open via novnc a new tab opens and i get "Something went wrong, connection is closed" On Windows 11 1. When i generate the console.vv and copy the password and hostadress + port to TigerVNC client everything work fine. TigerVNC tells me that connection is secured 2. When opening console.vv directly via RemoteViewer i get "Filed to complete handshake Error in the pull function 3. When i try to open via novnc a new tab opens and i get "Something went wrong, connection is closed" 4. When i run "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\VirtViewer\Remote viewer.lnk" --debug C:\Users\rezaa\Downloads\console.vv --gtk-vnc-debug I get : C:\Users\rezaa>"C:\ProgramData\Microsoft\Windows\Start Menu\Programs\VirtViewer\Remote viewer.lnk" --debug C:\Users\rezaa\Downloads\console.vv --gtk-vnc-debug C:\Users\rezaa>(remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.218: keymap string is empty - nothing to do (remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.264: Opening display to C:\Users\rezaa\Downloads\console.vv (remote-viewer.exe:9460): virt-viewer-DEBUG: 19:16:33.265: Guest (NULL) has a vnc display (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.271: ../src/vncconnection.c Init VncConnection=00000000070f1c90 (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.271: ../src/vncdisplaykeymap.c Using Win32 virtual keycode mapping (remote-viewer.exe:9460): gtk-vnc-DEBUG: 19:16:33.272: ../src/vncdisplay.c Grab sequence is now Control_L+Alt_L (remote-viewer.exe:9460): libsoup-WARNING **: 19:16:33.277: Could not set SSL credentials from '/etc/pki/tls/certs/ca-bundle.crt': Vertrauenswürdigkeitsliste konnte nicht aus /etc/pki/tls/certs/ca-bundle.crt befüllt werden: Error while reading file.
