Trying to setup my email server for sending reports, etc. and getting this error message. I have been searching around on help topics and the knowledge base with no real luck. I have used an online SMTP checker and verified the account is working, and I do have 2 factor and the app password configured. It seems as if something on the Ignition side is blocking. This is a standalone PC, not connected to any domain, so I am thinking it is not a DNS issue that I have seen in previous posts.

```python
com.sun.mail.util.MailConnectException: Couldn't connect to host, port: smtp.gmail.com, 465; timeout 10000;
  nested exception is:
	java.net.SocketTimeoutException: Connect timed out

```

Did you use the gateway test function?

Yes. This is what generated the timeout error.

This is a pretty straightforward network problem... probably a firewall or something.

There's very little of Ignition involved at this point. If you took a Wireshark capture you'd probably see Ignition send the TCP SYN and then nothing else.

Kevin. I have to agree with you on this. We did a backup of the gateway and installed it on one of our laptops, hot spotted the laptop and then sent the test email without any issues. I will have to get with the customer’s IT department. Thanks for pointing me in that direction.
