Hi

this error message means that your splunk instance has configured to use user which haven't right to send email to your configured smtp-server.

Here is instructions how to configure your splunk to send emails. https://docs.splunk.com/Documentation/Splunk/latest/Alert/Emailnotification

Be sure that your are using smtp-server which allow sending emails from your server. Usually there are some requirements which your client must fulfil before it can send email. You can get those from your SMTP server admin.

Also, could you please explain in more detail (example) about: "Usually there are some requirements which your client must fulfil before it can send email." 

Thank you.

Hello all,

I have a problem with my configuration smtp.
When I send e-mail I get this error :

2024-02-14 16:44:15,213 +0100 ERROR cli_common:482 - Failed to decrypt value: ***************************=, error: Read custom key data size=30

Someone has an idea?

This line in $SPLUNK_HOME/lib/python3.7/site-packages/splunk/clilib/cli_common.py was the source of an error when configuration initialization is slow...

 

 if err:
    logger.error(
        'Failed to decrypt value: {}, error: {}'.format(value, err))
    return None
  return out.strip()

 

There is a wallclock message that gets in the middle of the decrypt operation causing it to fail.

Changed code to this, and problem went away.

 

if 'took wallclock_ms' no in err:
    logger.error(
        'Failed to decrypt value: {}, error: {}'.format(value, err))
    return None
  return out.strip()

Hello,
We are facing the same issue.
How did you identify the wallclock message ? is it possible that for us is a different one?

I tried your solution after correcting the python 

 

if 'took wallclock_ms' not in err:

 

 but hasn't worked for us.
Thanks,
José
