Every day my email notification is telling me the updates for Box, Dropbox, Skype and TortoiseSVN have failed. They all fail with the same error "The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel."
Everything else is fine, it's just these four, always these four.
Thanks.
Sorry for the delay, this would be a firewall issue.
Thanks for the reply. Any idea where to start looking? Particular log file? It seems odd because it's just these that are affected, everything else downloads fine.
Try downloading the URL that's failing in a browser to see if you get an error from your web filter.
