SSL errors : "Unknown SSL protocol error in connection to"



We’re seing some weird intermittent SSL errors towards the twitter API from some of our servers (but not all). These errors only happen with the twitter API.

I can easily reproduce it by running this ruby script :

100.times { p HTTP.get('') }

I’ll get the following error intermittently :

curl: (35) Unknown SSL protocol error in connection to

Using OpenSSL 1.0.1e 11 Feb 2013

Have you seen this before ?



Hello, you solve this? I have the same error every day.


I’m also having the issue. Created a stack overflow post with more details:

The only answer did not work.
