Internet speed can, however, fluctuate due to various reasons such as maintenance works or old equipment. When this is the case, and you are trying to stream Hulu TV shows or movies, you will usually get an error. Sometimes it is displayed as Error code 3 and also associated with the more common errors like 503 (service unavailable) or 504 (gateway timeout error).
How can I fix error codes 3, 503, and 504?
1. Check Internet connectivity
2. Perform a power cycle
A complete power cycle improves streaming conditions by restoring the functionality of all devices and network connections. Therefore, switch off your devices (including modem and router). Wait a few minutes, then switch them back on and see if it helped.
3. Update or reinstall the Hulu app
We recommend this step just for reassurance since most probably the problem should be solved with the previous fixes. Yet, keeping your Hulu app updated is essential to ensure a seamless performance. As a last resort, uninstall the app and reinstall it on your media player. Having mentioned all the above, don’t forget that sometimes the error can occur on Hulu’s end. In this case, you just have to wait for the service to restore the connection.
