Issue with Audio2Face Unreal Plugin: API Key Error

Gaming and Visualization Technologies Engines Unreal
1

After configuring everything in Unreal Engine, it was working well but now it doesn’t work anymore.
When I input the API key and try to test it in Unreal Engine, I get an error.

Q1: Is this issue unique to me?
Q2: Is everyone experiencing this issue?
Q3: Is this by any chance a test service and not the official service?

I’m experiencing this issue as well! I downloaded the Kairo sample project and the ACE plugin today from NVIDIA ACE - Get Started | NVIDIA Developer and set up everything according to NVIDIA ACE 2.1 Plugin — ACE documentation latest documentation (I only skipped the section “Animating a Character from a Sound Wave Audio Clip” as I have no idea which blueprint to use). But it didn’t work once

This is my output log:
LogACERuntime: sending A2X wav file [redacted]/audio_samples/Claire_neutral.wav
LogACERuntime: [A2X SID 5] Started A2X session at https://grpc.nvcf.nvidia.com:443

Hello and welcome to the NVIDIA developer forums!

Sadly I am not able to help you right away, but I reached out internally to see if and how we can address this.

Thanks!

Hello, Markus! Does it look likely the issue will be solved this week?

Welcome @jet4 and @brett46,

as far as I was informed the server issue should be resolved again. It would be good if someone in this thread could confirm.

Thanks!

I keep having the same issue today.

Thanks, I forward this, the API access should have been resolved by now.

It seems one of the reasons why you might see issues with connecting to NVCF is that you could have run out of usage credits for the Cloud service.

I am not detailed familiar with the credit usage of NVIDIA NIM | audio2face, but the number of free credits is limited.

You should see the available inference credits in your developer account for NIMs.

So if you could check that, that would be helpful.

Thanks!
