昨天发现登陆阿里云失败，我以为是家里网络问题，今天在公司发现还是有这个问题，发现不仅仅是Chrome报错，而且Safri也报错。
今天在网上找到了解决方案：
Safari could not establish a secure connection to Wikipedia?
wikipedia works but i'm suddenly having this problem with vimeo and soundcloud not loading. both worked fine using current safari and chrome yesterday. also embedded vimeo videos no longer play on my website. firefox seems to be OK.
update: pasting the terminal code from above fixed this issue for soundcloud and vimeo with safari and chrome.
sqlite3 ~/Library/Keychains/*/ocspcache.sqlite3 'DELETE FROM ocsp WHERE hex(serialNum) IN ("040000000001444EF03E20", "040000000001444EF04247");'
