Hi ALL,

Inside my logs of logstash i am receiving the error as such :

[2022-02-22T17:00:11,265][ERROR][logstash.javapipeline] A plugin had an unrecoverable error. Will restart this plugin.

The cofiguration this error is pointing is :

port =\> 93  
user =\> "_**@whopper.microsoft.com"

fetch\_count =\> 600

folder =\> "\*\*\*\*\*\*\*"

# folder =\> "\*\*\*\*\*\*"

```
delete => false

```

# content\_type=\>"text"

# sincedb\_path =\> "/dev/null"

# uid\_tracking =\> "false"

}

}

Exception: Net::IMAP::NoResponseError

```auto
Stack: ... uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/net/imap.rb:1253:in ` send_command'
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/net/imap.rb:441:in `login'`

```

The login function sent the username and password to the IMAP server and it got a "NO" response, meaning authentication failed.
