Timed out while checking out a connection from connection pool

To Whom It May Concern:

I made it with Auth0.NET SDK to get the token.

var authenticationApiClient = new AuthenticationApiClient(…);
var token = await authenticationApiClient.GetTokenAsync(new ResourceOwnerTokenRequest{…});
return token;

I checked the log that is provided by Auth0 because there were some failure cases of logining with the feature.
When I checked the log, it loged Failed Exchange and “Timed out while checking out a connection from connection pool” message

Would you tell me what the cause of the problem is?

And does it have connection limit?

Hi @yhkimjjang,

Welcome to the Community!

It looks like this may have been related to a brief outage that occurred this morning. If you think it was not related to this, and are still experiencing the error, please let me know and we can look deeper.

Thanks,
Dan
