You may have noticed an issue when using Sauce Connect Proxy with not being able to connect to your web applications at localhost when using certain ports. For example:
- Spin up a local server serving content on port
- Start Sauce Connect Proxy.
- Open a Sauce Session in Safari 8 or 9, or Edge, and try to load
You won't be able to access the content.
- Start another local server on port
localhost:3000in the same session
You will be able to access the content.
This will happen with Safari 8 and 9, and Edge browsers. The issue is these browsers will never send localhost URLs via a proxy, and always use a non-proxied connection to reach localhost.
You have two options for a workaround.
- Modify the hosts file in the machine running Sauce Connect Proxy. Just add a fake domain, such as
myname.local, that points to
127.0.0.1. Then, point your tests to that URL instead of
localhost. This will skip the localhost proxy entirely and prevent the issue, and may even improve the performance of your tests.
- Use the Sauce Connect localhost proxy to connect over a different port. The answer to the question "Can I Access Applications on localhost" in the Sauce Connect Proxy FAQs contains a list of all the ports you can use with Safari.
