Reauthenticate on invalid token error?

[NiteAx]

Hey, have been using the custom token example for my project and it works great for my intended use case. I noticed after an hour or so the token becomes invalid, which makes sense but is there a way to reauthenticate on invalid token error?

The authentication token is auto refresh or regenerate but there is an exception when your device time was changed after the token was generated and the timestamp in the token and system time are not synched.

To force token refresh or regenerate, please see this topic and also this issue (this for Firebase ESP Client library which can be applied to Firebase ESP8266 and Firebase ESP32 libraries too)

Thank you, will try these. Now just got to wait 59 minutes.

To test, use config.signer.preRefreshSeconds to pre refresh the token before its expiry time.

config.signer.preRefreshSeconds = 3420; // force token refresh in 3 minutes (57 minutes earlier)
