Error After New Contact Added to List


Error After New Contact Added to List

I seem to have a weird bug that has started happening right after we switched to a new server. Our emails had no problems being created, but now whenever a new contact is added to the list, the following happens. If we remove the new contact it starts successfully sending email again. I don't understand why this is happening.

  [0] => Array
      [error_key] => http.status.bad_request
      [error_message] => Inalid Content.


I found other threads saying to check for null in any fields and there aren't any. Why would a new contact cause emails to stop functioning?
