An issue started today where i cannot connect to Mailgun's SMTP. This was not previously a problem

root@1dceb4cc5bb4:/application# telnet smtp.eu.mailgun.org 587

Trying 34.95.107.114...

telnet: Unable to connect to remote host: Connection timed out

Ive also tried:

telnet smtp.eu.mailgun.org 2525

And
openssl s_client -connect smtp.eu.mailgun.org:465

Same issue. Wonder if something has changed?
