I have an SSL cURL request that fails from a single machine with the following error:

curl: (51) SSL peer certificate or SSH remote key was not OK

This error seems to have popped up overnight, and isolated to a single machine. The request was working, then the machine was shutdown. Today, the machine was powered up and the request no longer works.

Details:

Machine is running linux 3.12.28
Multiple other machines have no problem with the same request, all on the same network.
The network of the machine in question seems to be fine otherwise

Things tried:

Setting the nameserver in /etc/resolv.conf to 8.8.8.8
Power cycling
Disabled all but one network interface

Has anyone had this problem before? What did you do to fix it? Any ideas for further debugging? Thank you.

Have you checked the time of the machine? The correct time (more or less) is necessary to validate the certificates. – Steffen Ullrich Mar 23 '15 at 21:33
Great suggestion. I just checked, and the time is correct. – r_robotics Mar 23 '15 at 21:44

Try using `curl -v` or `curl --trace -` (followed by the rest of the curl arguments) on the problem machine and a working one and add the results to your question. – Paul Haldane Mar 23 '15 at 22:13
Great! Thank you. I will try that and report back with my results. – r_robotics Mar 25 '15 at 00:06
