CSCvf23231 - WSA is showing "Certificates signature verification failed" while trying to upload a sub-ca certificate

[pierre.brueggemann]

We use several S100V appliances with 10.5.1-296 running on it. I can not upload a sub-ca certificate to it to activate https proxy. I get the message "Certificates signature verification failed" every time.

I use a Microsoft CA root server and a key size of 2048.

Any hints on solving this problem?

Thank you

Regards

No one else has this problem or knows how to solve this?

In bug tracker ist says in 10.5.1-296 this is fixed, but it occurs here, too.

Thank you

Try installing the root CA certificate in the trusted root certificate WSA store.
Network > Certificate Management > Certificate Lists > Manage Trusted Root Certificates.

And then I was able to put the sub-CA in the HTTPS Proxy.
