Hello, I’m having problems uploading large files (3GB) to a server with SSL enabled. I’m using nginx 1.4.2 + passenger. Files around 1GB large work fine. My /tmp mount is large enough to handle files of that size. I guess I’m missing something. I read about a SSLRenegBufferSize parameter for the apache server - is there a similar directive for nginx that I’m missing? I appreciate any hints. My nginx configuration: nginx version: nginx/1.4.1 built by gcc 4.4.5 (Debian 4.4.5-8) TLS SNI support enabled configure arguments: --prefix=/opt/nginx --with-http\_ssl\_module –with-http\_gzip\_static\_module --with-cc-opt=-Wno-error –add-module=/usr/local/rvm/gems/ruby-1.9.3-p392/gems/passenger-3.0.19/ext/nginx Here is the curl output that I get when trying to post a 3GB+ file: curl -v -X POST -d @BIG\_TEST\_ARCHIVE\_3.zip [https://shared.com](https://shared.com) - About to connect() to [shared.com](http://shared.com) port 443 (#0) - Trying 199.58.85.103… - connected - Connected to [shared.com](http://shared.com) (199.58.85.103) port 443 (#0) - SSLv3, TLS handshake, Client hello (1): - SSLv3, TLS handshake, Server hello (2): - SSLv3, TLS handshake, CERT (11): - SSLv3, TLS handshake, Server key exchange (12): - SSLv3, TLS handshake, Server finished (14): - SSLv3, TLS handshake, Client key exchange (16): - SSLv3, TLS change cipher, Client hello (1): - SSLv3, TLS handshake, Finished (20): - SSLv3, TLS change cipher, Client hello (1): - SSLv3, TLS handshake, Finished (20): - SSL connection using DHE-RSA-AES256-SHA - Server certificate: - subject: OU=Domain Control Validated; [CN=shared.com](http://CN=shared.com) - start date: 2013-05-06 12:15:19 GMT - expire date: 2016-05-06 12:15:19 GMT - subjectAltName: [shared.com](http://shared.com) matched - issuer: C=US; ST=Arizona; L=Scottsdale; [O=GoDaddy.com](http://O=GoDaddy.com), Inc.; OU=[Sign In](http://certificates.godaddy.com/repository); CN=Go Daddy Secure Certification Authority; serialNumber=07969287 - SSL certificate verify ok. > POST / HTTP/1.1 > User-Agent: curl/7.24.0 (x86\_64-apple-darwin12.0) libcurl/7.24.0 > OpenSSL/0.9.8x zlib/1.2.5 > Host: [shared.com](http://shared.com) > Accept: _/_ > Content-Length: 1590530720 > Content-Type: application/x-www-form-urlencoded > Expect: 100-continue \< HTTP/1.1 100 Continue - SSL read: error:00000000:lib(0):func(0):reason(0), errno 60 - Closing connection #0 curl: (56) SSL read: error:00000000:lib(0):func(0):reason(0), errno 60 Posted at Nginx Forum: > **[SSL + Large file uploads (3GB+)](https://forum.nginx.org/read.php?2,240727,240727#msg-240727)** > > Hello, I'm having problems uploading large files (3GB) to a server with SSL enabled.

At the end of the day the cause was a timeout due to long processing in the background. Thanks for having a look anyways!
