I just noticed this today. AFAICT, it only affects https to www.google.com and other Google subdomains (first noticed on docs.google.com). It does not affect Firefox.
Odder still, I have two fully up-to-date (AFAICT) Xenial machines, both amd64. One of them connects to https://www.google.com just fine, the other produces the error shown here. https to other sites, e.g. Launchpad, gitlab, github, etc. all work fine. No proxies involved, no weird networking setups afaict (I did have bridge networking set up on the failing machine, but disabled that and still had the problem after a reboot). Running chromium in --verbose mode on the console didn't show up anything obvious. I even disabled all plugins and it still had the problem after a browser restart. But at least I have two systems that are exhibiting different behavior, so maybe that can help debug the issue. I'm at a loss as to what to look at next. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to nss in Ubuntu. https://bugs.launchpad.net/bugs/1520568 Title: All queries fails when 'google' is used: ERR_SSL_PROTOCOL_ERROR Status in chromium-browser package in Ubuntu: Confirmed Status in nss package in Ubuntu: Confirmed Bug description: Latest libnss3 upgrade have broken all the browser's queries; no matter of which is used.
