Hey @voratham. Can you give us more details about the server-side of your Unleash setup? Are you using proxy, edge or frontend API? What version are they? Have you made any upgrades recently when the error reporting started?

unleashorg/unleash-proxy:0.8.1

The error you're seeing is probably from line 411: https://github.com/Unleash/unleash-proxy-client-js/blob/main/src/index.ts#L411C16-L411C16
This error means that you send HTTP request but the response never arrived.
In this case we do: console.error('Unleash: unable to fetch feature toggles', e);
https://github.com/Unleash/unleash-proxy-client-js/blob/bac049d8ec641bc7c2f194a3e65add705b0b6ba4/src/index.ts#L437C17-L437C78 which you're seeing in sentry.
There's a few reasons it may happen but the most typical case is there's a network connection problem. Someone using a mobile device goes offline. Or someone with a slow connection times out their request.
Here's a video explaining that with users going offline or requests being blocked by the browser you'll see those errors:

I have some question i should upgrade unleash-servser same? it will breaking change or not ?

You can upgrade proxy separately from the unleash-server. However to benefit from all the improvements (security patches, product enhancements, bug fixes) that we're making every day I'd recommend to also upgrade unleash-server. Here's a detailed info about upgrade: https://docs.getunleash.io/using-unleash/deploy/upgrading-unleash. From the SDK perspective there are no breaking changes.
