LTM Update Check behind proxy

All,

 

I have multiple F5 LTM VEs being used as LTM ADCs that I need to update, all of which are in customer environments with upstream proxies that can't be bypassed. All of them say "no response from update server" but I can resolve, and ping and there are no active 443 ACLs preventing traffic.

 

It looks like it's complaining about certificates? I've seen a couple devcentral posts about this, but no real resolution. I just want to check for updates, that shouldn't be that hard right?

 

Any advise?

 

Thanks,
