#StackBounty: #ssl #https #http #curl #wget curl + wget cannot make https connections

Bounty: 50

My Ubuntu 16.04 system has the following problem:

  • wget and curl hang indefinitely when connecting to a server with HTTPS
  • Both programs work fine with HTTP

Example for curl:

curl -vv https://google.com
* Rebuilt URL to: https://google.com/
*   Trying 172.217.0.174...
* Connected to google.com (172.217.0.174) port 443 (#0)
* found 127 certificates in /etc/ssl/certs/ca-certificates.crt
* found 513 certificates in /etc/ssl/certs
* ALPN, offering http/1.1
# … timeout after some time

Things I have tried:

  • update curl and libssl with apt

How can I diagnose this problem? The system is a "server" so I have no GUI available to check if e.g. a browser works with TLS.

The computer is an Intel NUC 6i7kyk. I’ve seen this problem on two different computers of this make, but never on any other system.
