I am facing the same problem. I had one ssl certificate setup for the
following domains:
firstdomain.com
*.firstdomain.com
a.firstdomain.com
b.firstdomain.com
a.seconddomain.com
b.seconddomain.com
When i read that it could be due to multiple different domains using the
same ssl certificate, i rem
do want to add the cert I was using was subdomain wildcard and the blocks
where for different subdomains so that should not have been a problem with
the cert.. maybe its an access issue to the cert? (nginx can't access it
multiple times at the same moment or something)

Yeah I removed the double blocks and it solved the problem...
The 'possible bug' though is that the problem seems completely random..
instead of giving error all the time sometimes it works and sometimes it
doesn't... Just refreshing the site a few times and it worked..
So it looks like Nginx just
I am facing the same issue on my Debian 7 Server. I downgraded to
1.0.1e-2+deb7u12 version of libssl1.0.0 and restarted nginx but the issue is
still occurring for me. I can still see the same logs.
I also tried following these instructions(installed the deb packages made by
these instructions) but

Here's what we've learned so far:
The issue is related to a new security feature that blocks TLS Fallback,
which is a client that connects with one version of TLS, then tries to
downgrade the connection and connect with a lower TLS version.. It was a
feature made in light of the Poodle SSL vulnera
Out of thin air, I suspect it is a certificate problem.
You seem to have configured *the same* certificate (and private key) for
those 2 domains. Since certificates are generally tied to a single domain,
that could explain errors.
Another idea: have you checked nginx has been built with SNI suppor
I found myself with the same problem and found the cause (and obvious
solution).
On my nginx server I run various website and they all have their own server

Some sites are on different IP's and some are on the same IP.

First off, thanks to all who contributed to this thread. I must admit I did
not understand much of it, however as someone plagued by this bug (we have a
bunch of cherrypy REST servers talking to iOS and Android clients and have
seen a lot of those fallback errors), I must admit I'm a bit of a loss
Just an update: as of today, even Debian provides
libssl1.0.0:1.0.1e-2+deb7u16 which still generates these error logs, so it
looks like the only way is still to fallback to
libssl1.0.0:1.0.1e-2+deb7u12.

That surely helps. So as of now the only way to resolve the issue is going
back to u12 version of libssl?

I should specify that I agree with what is happening. We have clients that
are falling back under normal conditions, and the latest libssl that
implemented fallback prevention for TLS is stopping. I have downgraded our

I had to start looking at this issue again now that yet another openssl

downgrading SSL, I am able to gather more information.
This morning, I updated the libssl libraries and restarted nginx, and the

You are absolutely correct, but I figured you would want a working

bug. Knowing that it worked for you also increases my own comfort that the

The errors went away, and now the only errors I see in our logs relating to
SSL are handshake timeouts when I turn debug logs on.
Now that I think about it, though, isn't this to be expected? The errors

Eric,
Did you try to downgrade your libssl to the previous version I mentioned
earlier? Would love to hear if your issues go away.

I just finished running an experiment that has shed some light on the issue.
It has not yet been solved though.

I have been fighting a similar issue with SSL handshake issues for the past
few days. After reboots and upgrades for GHOST, we started seeing errors
like this in our error logs constantly:

Prior to this issue starting, we had not changed our ciphers in several
months. I have tried changing them once since. We have also tried restarting
nginx several times on each server to clear the cache, but it has not
helped.

We are using round-robin DNS to distribute requests to three servers
all running identically configured nginx. Connections then go upstream
to HAProxy and then to our Rails app.
About two weeks ago, users began to experience intermittent SSL
