Solved! I cleared all the cache and certificates on my java control panel
Good morning, I did some updates with lifecycle controller, one of these was iDRAC 7 2.65.65.65 and that update was stuck, after 2 hours I did a cold reboot and all worked fine, but now the console is not working anymore: I get stuck when the java application does the verification of the program, how can I solve this? I have a PowerEdge R720. Thank you to all people will reply [IMAGE]
