Is there a function to automatically restart when it is a "UNAVAILABLE" error?

[JIHoon Ock]

Thank you for looking at my question.

Sometimes errors occur in the process of inquiring campaign information.

Error "NoRouteToHostException" and code "UNAVAILABLE" are returned.

However, I looked up the log and it seems to automatically retry in the "UNAVAILABLE" code error situation.

If you look at the log, it looks like you're trying a total of nine times until you succeed.

Am I right in guessing?

If the guess is correct, can I know the maximum number of retries I try?
