I have the webserver behind a firewall blocking all outbound traffic and could not get the koha installer to launch. After digging into the logs I saw the same connection timeouts to swagger.io As soon as I opened up our firewall the installer loaded. You can also reproduce this by dropping something bogus in your /etc/hosts file for swagger.io and restarting plack For example - 127.0.0.1 swagger.io -- You are receiving this mail because: You are watching all bug changes.
