Mail server send error time out

Greetings ive setup all my dns records to point to my linux instance in vultr. I think everything is setup correct but when i try to send an email using rainloop im getting

[{“address":"uersou@gmail.com”,“delay_reason”:“connect to alt4.gmail-smtp-in.l.google.com[142.250.153.26]:25: Connection timed out”}]

Suggestions?
Thanks.
