CIS can not be updated

CIS can not be updated, but opened a proxy server will be able to update.
why? I am Taiwan’s network.

Can you try again several times the next day or two? That is to see if it the problem is temporarily or not. Has it worked before?

Now update okay.
But my CCAV can’t scan files now…
What happen Server? CCAV can’t cannect server now…

The problem with CCAV is not related to CIS. The problems with CCAV and the connection are work in progress.
