When tests are run using Sauce Connect and the browser is not able to connect, or times out when trying to connect to a particular site or server, the browser on the test VM will display a Zero Sized Reply error.
This is the message that our Squid cache, which the Sauce Connect Proxy application is built on, gives when something is not right.
This error message can occur for a number of reasons known to the Squid project. If you encounter this error in either your automated or manual tests, please open a new support ticket at help@saucelabs.com and include the following information:
- Command-line flags used to start the Sauce Connect instance
- Version and build number of the Sauce Connect instance
- Operating System used to run Sauce Connect
- The logfile produced by Sauce Connect, ideally when run with the '-v' flag (verbose mode)
