Raw message
tvq-st-103
Likely causes
- A network problem prevents the device reaching Netflix.
Choose the branch for the actual device
Netflix explains this code as a network problem and supplies different device branches. Our recommendation is to record the model first. Fire TV starts with More Details > Reload Netflix; that menu is not a universal first step.
On smart TV, retain the browser-test result
The smart-TV branch uses a phone or computer on the same network to visit netflix.com/clearcookies and sign in. This clears that browser's Netflix session. If NSEZ-403 appears, Netflix asks you to wait and try again later. With no browser error, continue its device steps.
