(technical info: error group 123 is SSL, and code 1502 is “received unexpected handshake from peer”) https://t.co/v71RmOi2dp
Switch’s latest system update is out, fixing an eShop bug and more under the hood
UPDATE: Nintendo has temporarily suspended the distribution of the update
The Switch has received its latest system update, and while relatively minor it will fix an eShop bug for some players.
Version 12.0.3. was released yesterday, and according to the official Nintendo patch notes, all it adds is “general system stability improvements to enhance the user’s experience”.
However, Switch dataminer OatmealDome investigated the actual changes made to the Switch’s firmware and noted on Twitter that there were changes made to:
- the OS kernel and key services
- SSL (for creating secure connections to a server)
- the system’s list of banned words
UPDATE: Nintendo has temporarily suspended the distribution of Switch’s latest system update, although it hasn’t offered a reason for doing so.
ORIGINAL STORY FOLLOWS: OatmealDome then tweeted again a couple of hours later to give more information on the SSL changes, which were seemingly made to fix an eShop bug.
Some players had been recently claiming that they were encountering an error code called 2123-1502 when trying to access the eShop.
According to OatmealDome, the 123 error group relates to SSL, and code 1502 refers to the console “receiving [an] unexpected handshake from [a] peer”. Therefore, this update appears to fix that error code for anyone experiencing it.
The last major Switch system update was version 11.0.0, which rolled out at the end of November 2020.
It added a Switch Online app to the home menu and made it easier for players to transfer screenshots and videos to a smart device or computer.
It also allowed users with multiple Switch consoles to automatically download backed up save data from the cloud on each system.
