Custom certificate - disable access to web admin

I have installed a custom certificate to USG110. USG110 confirms Validation Result=successful

But when I select the custom certificate for https in Configure>System/www>Server certificate the FW blocks for web access after about 15 seconds. 

I can bring it back to life by using SSH to switch to default certificate.

Any ideas why this is not working? The FW have just been installed and there are no special configuration setup yet.
I have installed the trusted certificate as well. 
Firmware is latest version 4.32 (tried also 4.31 with same result).

Thanks for any input.

    Solved it myself.
    The certificate needs to be imported without the trusted certificate chain. These need to be imported separate in the trusted tabs.
    The certificate works now.
