The watcher email action send error,as follows:
"error": {
"root_cause": [
{
"type": "messaging_exception",
"reason": "failed to send email with subject [xxx] via account [smtp_account]"
}
],
"type": "messaging_exception",
"reason": "failed to send email with subject [xxx] via account [smtp_account]",
"caused_by": {
"type": "authentication_failed_exception",
"reason": "535 5.7.8 Error: authentication failed: authentication failure\n"
}
}
But sometimes is ok,why?

2

Do all the nodes have the same settings? Cluster/shard changes could cause a different node to execute the watch (depending upon the version).

3

Yes,all node is set

4

Is it possible that you have multiple mail servers behind the destination address that you are hitting with watcher, where one of those servers is rejecting with 535 5.7.8 Error: authentication failed: authentication failure?

5

Is it the same recipient on mails that work and those that don't?
