Provider did not reconnect successfully within 5s. Emitting ERROR event...

We are getting intermittent errors while trying to fetch flags from AWS APpConfig. Please see logs with DEBUG enabled.

Without Debug Flag enabled for Flags, below were the logs.

Does anybody has any idea about what could be the cause.

Below are the dependencies we are using

api 'dev.openfeature:sdk:1.20.1'
api 'dev.openfeature.contrib.providers:flagd:0.13.0'

and Flagd binary version is: v0.16.0

Start by reproducing the intermittent AWS AppConfig fetch failure with the listed Java dependencies and flagd v0.16.0, keeping DEBUG logging enabled. Inspect the HTTP fetch path shown at http/http_sync.go:127 and correlate it with the provider state transitions and reconnect timing. Done means the cause of the failed reconnect is isolated and a verified resolution or clearly documented reproduction is available.
