• Firebase Component: Remote Config
• Component version: 21.0.1

[REQUIRED] Step 3: Describe the problem

I set firebase remote config fetch timeout to 5 seconds, but it is ignored and default one (60 seconds) is used. To test this I setup charles proxy with following throttling configuration:

Steps to reproduce:

1. Setup proxy to delay all communication for 100 seconds
2. Run app with timeout set to 5 seconds
3. FirebaseRemoteConfig.fetch blocks for around 60 seconds

Relevant Code:

val firebaseRemoteConfig = FirebaseRemoteConfig.getInstance()
firebaseRemoteConfig.setConfigSettingsAsync(
    FirebaseRemoteConfigSettings.Builder()
        .setFetchTimeoutInSeconds(5)
        .build()
).await()
firebaseRemoteConfig.fetch(remoteConfigFetchInterval).await()
firebaseRemoteConfig.activate().await()

private fun <T> Task<T>.await() = Tasks.await(this)

Hi @adam2603 thanks for reporting. I’ll try to replicate this and see what we can do here.

This is still happening - at least on 21.2.0. Sometimes (very very rarely) each fetchAndActivate() takes 20 seconds on my Pixel 4a. No amount of process restarts will fix it. It just takes 20 seconds every time. Setting setFetchTimeoutInSeconds() to for example 5 seconds doesn’t help at all. It seems that the Firebase service is somehow “stuck”, maybe the connection works as expected but some other parts of the Firebase Config code now cause a large delay. Rebooting my device has fixed the huge 20+ second delays. So this confirms that it’s a Firebase service issue on the device (since uninstalls or process restarts didn’t fix it, only device reboot).
