Timing out trying to connect to dockerhub

ERROR: Get https://dockerhub.xyzcorp.com:5321/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

MTU is already 1500 or lower:

I’m totally blocked at this point. Any suggestions?

It sounds like you’re simply having a network timeout error. Are you able to reach https://dockerhub.xyzcorp.com:5321/v2/ from your web browser? Is that indeed the correct port? Is it possible that there’s a firewall blocking traffic between your docker host and that registry?

Weird. I posted to the Docker forum, and by the time I got done with that and reran compose, it started working:

Next time I’ll (duh) try pinging the server.
