I'm having trouble using Basecamp in Chrome: it's started to error out most of the time (but not 100% of the time) with
Error 205 (net::ERR_CERT_UNABLE_TO_CHECK_REVOCATION): Unknown error.
I'm not having any problems logging in or using it in other browsers. I have a about a dozen Addons/ plugins, but I can't say this started right after installing a specific one. How can I debug this issue?
