I need to take 443 traffic to a public address and proxy it to port 81 on an internal server. In the reverse proxy settings. I have it set to 'Provide HTTPS for HTTP backend' SSL Port is set to 443 I have a certificate imported into the Reverse Proxy config. I have the Backend IP address set the 192.168.10.10:81 (IP of the internal server) When you go to the public url you get a TLS error Failed to establish a secure connection to 127.0.0.1 The system returned: (104) Connection reset by peer (TLS code: SQUID_ERR_SSL_HANDSHAKE) Handshake with SSL server failed: [No Error]. Gary, I was able to reproduce a similar error message of the reverse proxy to yours. The error arises when I reverse proxy (in SSL mode: Use SSL = Yes) a webserver but my backend Apache is not offering a listening socket on 443.

So it seems that there is an issue with the communication between the reverse proxy and the backend server. However, feel free to Contact Barracuda Networks Technical support. Our Agents can check your configuration to solve the issue. Regards, Matthias. ![]() I'm currently getting the error, socket.error: [Errno 54] Connection reset by peer when I use requests.get(url, params=kwargs) and the params contain large bodies of text. If I truncate the two large bodies of text to less than 2,900 characters each, it works. If I run the same get request from the command line using curl it works. I'm using requests version 0.6.1 that I installed using, pip install python-requests. I'm not sure how to tell you to replicate the issue because I'm using the library to add a newsletter to my sendgrid account and I don't want to post my api username and password in issue ticket.:) To test from the command line using curl I created two files that each contained plain text and html text that was urlencoded using a. Then I ran the following command. Sorry, I forgot to provide the full traceback. Here is the traceback I get when I get the error. Also, I'm not understanding how to use the HTTP proxy and why that would make a difference when it works from the command line with curl. It's strange that I get the same error with similar data, the only difference is that in my case I do not have big list or size of parameters. The same request made via CURL works fine but via requests gives me this error. Requests.exceptions.ConnectionError: HTTPSConnectionPool(host='sbarnea.com', port=443): Max retries exceeded with url: /jira/rest/api/2/group?groupname=jira-administrators&expand=users (Caused by: [Errno 54] Connection reset by peer) Even more interesting, it seems that the request does not even reach the web server. Any idea what it could be cause? Still there is something strange: in both cases I used Python, when tested from OS X it failed, when tested from Ubuntu it worked. Normally I wouldn't touch the default settings for SSL, but I run a SSL report and tried to solve most warnings: FIPS requires: SSL v2 and SSL v3 are disabled (only TLS version protocols in use) Also read about BEAST attacks. Check it here: So, I wondering if it's possible to fix this, clearly if it works with Python on Ubuntu, it cannot be specific to all python versions. Just to give a bit of closure on the subject. If your webserver doesn't allow TLSv1 then you will get TLSv1.1 and 1.2 with python 2.7.9 (due out in december 2014). Ensiklopedia keris pdf download windows 7. However you can also install PYOpenSSL and inject that into urrlib3 () which seems to allow use of requests for a webserver that has disabled TLSv1 with python 2.7.6 (and probably others). Import urllib3.contrib.pyopenssl urllib3.contrib.pyopenssl.inject_into_urllib3() But really, the webserver should probably not be deprecating something which forces people to jump through this many weird hoops.
