Hi @Tsahi_Etziony ,
on the GW run R80.20 Take 141.
So this shouldn't be a problem.
No installing a specific jumbo via smartconsole also doesn't work currently.
When I try to install a hotfix on smartconsole via Select Gateway -> Actions -> Install Hotfix a new window is opening inside the smart console. It looks like the smartconsole is trying to open a https connection to the Management Server. But I receive a error message as described in my first post.
So it looks like the smart console is trying to connect to the Management Server via https and is getting an error.
I would try to find out more but I was not able to find a document that explains the traffic flow and why the smart console is is failing to connect to the management server
I guess this is caused by the same problem, why also Recommended Jumbo stays on "N/A".
I would require more information, about what happens when I press the "install hotfix" button and how the recommended Jumbo display is working.
For your Information, "Recommended Updates" is working perfectly fine for gateway and management.
I also added a screenshot from the error message.
Kind regards
Niklas
