The information in this article can help you when you're unable to access an online feature, such as the Nintendo eShop, on Nintendo Switch and receive the error code 2811-5003.
This error code indicates an error occurred when connecting to the service, likely the result of the network environment.
This error may be the result of the DNS used, or issue related to wireless interference, weak signal strength, or an unresponsive router.
Restart the Nintendo Switch console.
To restart the console, press the POWER Button for three seconds, then select Power Options and then Restart.
Create a new Internet connection.
Set up a new Internet connection, ensuring that you are attempting to connect to the correct network, and that you are receiving a strong wireless signal from the network.
Manually enter an alternate DNS.
If the DNS you are attempting to use is not working, entering an alternate DNS may resolve this issue.
Power cycle your home network.
Restarting your network devices may resolve this issue if it is related to the devices being unresponsive.
Move the Nintendo Switch console closer to the wireless router.
If possible, place the Nintendo Switch within 10 to 15 feet (3 to 5 meters) of the wireless router to improve the signal strength during troubleshooting.
It may be helpful to remove the Nintendo Switch console from the Nintendo Switch dock while troubleshooting, and then return the console when troubleshooting is complete.
Move any metal objects or electronic devices away from your Nintendo Switch console and wireless router.
Metal objects and electronic devices may interfere with wireless signals. If you have any of these, such as filing cabinets, speakers, power strips, glass, or cordless phones, next to your console or wireless router, move them away.
If supported by your router, connect to a different wireless band.
Many routers support both the 2.4Ghz and 5Ghz frequency bands. If your router supports both, set up a new Internet connection and connect to the band you are not currently connecting to. Many routers will have default SSID names that label whether the connection is 2.4Ghz or 5Ghz, but if you're not sure, contact your Internet Service Provider for assistance with how you can review this information within your router's settings.
Situation not resolved
If you would like to continue troubleshooting potential issues related to the wireless router, contact the router's manufacturer for assistance with performing the following steps:
Removing or disabling parental controls on your router
Updating the wireless router's firmware
Resetting the router back to its factory default settings
