Hello @Gregonmac  From the Error trace, it can be seen that the Authentication failed while connecting. We have seen scenarios in the past where the issue is with having special characters in the password. Do you have any special characters in your password?  If yes, you can give it a try using a below approach: Encode the password that has special characters. For example: a. Password with special characters: Aj8T2heD1cLMsV8qKIULn8g/tfy/+VO3yPLbhJfXQ9U7 b. Encode the password with following command: python -c "import urllib; print urllib.quote_plus('Aj8T2heD1cLMsV8qKIULn8g/tfy/+VO3yPLbhJfXQ9U7')" c. Use the encoded password in your Alert Publisher settings: Aj8T2heD1cLMsV8qKIULn8g%2Ftfy%2F%2BVO3yPLbhJfXQ9U7  Let me know if this helps.   Thank You,  Tarun ... View more
