I have been trying to configure my rails project to use SSL (as application wide) with thin (by adding thin gem and placing config.force_ssl = true to application.rb) but as a result, I have an annoying problem.
When I start my rails server using rails s and try to access http://localhost:3000 it redirects to https://localhost:3000 which is correct, however it will complain about missing SSL certification..
SSL connection error
Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have.
On the other hand, If I start my application using thin start --ssl and try to access http://localhost:3000 it doesn't redirect to https://localhost:3000 and complains about this:
No data received
Unable to load the webpage because the server sent no data.
but by accessing https://localhost:3000 it just shows certificate warning but it all works after agreeing to continue.
So my question is, How can I make http to https redirection work when using SSL with thin in (development mode)?
Perfect answer would contain possibility to start server normally by using rails s while SSL would be enabled application wide and accessing http redirects to https and all works! :)
Thanks in advance, have been searching for hours but cant find an answer.
You should install your own openssl signed certificate. You can find more information on this page
Your PC as (localhost) can self sign SSL certificate and your browser can accept it, but i think that browser will not automatically accept certificate with security on that layer. Maybe to try to add your localhost certificate to the browser ?
Verify config/environments/development.rb has the following line
config.force_ssl = true
Refer the post thin with ssl support and ruby debug and the responses(from nathan and shree) that has more information on this subject:
Use ngrok (https://ngrok.com/). It's free. Installation is easy.
Just start up your server, then in another terminal window run
ngrok http 3000
ngrok will give you an address that loops back to your dev machine - something like http://randomstringhere.ngrok.io
Put that in your browser and you'll see it redirect to https://randomstringhere.ngrok.io, still routing to your server on port 3000
Here is the simplest solution.
