I created a droplet recently (Ubuntu Docker 18.06.1~ce~3 on 18.04). And I realize emails couldn’t be sent by my application.
I’m using SendGrid’s API.
It works perfectly from my local machine.
I can’t even ping api.sendgrid.com from my droplet.
PING api.sendgrid.com (159.122.219.48) 56(84) bytes of data. — api.sendgrid.com ping statistics — 328 packets transmitted, 0 received, 100% packet loss, time 335312ms
It works well if I try locally:
$ ping api.sengrid.com PING api.sengrid.com (85.128.131.76): 56 data bytes 64 bytes from 85.128.131.76: icmp_seq=0 ttl=50 time=85.898 ms 64 bytes from 85.128.131.76: icmp_seq=1 ttl=50 time=79.936 ms 64 bytes from 85.128.131.76: icmp_seq=2 ttl=50 time=112.295 ms
Why is that endpoint not reachable ? I tried other endpoints without issues.
