Follow the set up and I get to this point:

How can all DNS checks pass and then not be able to reach Openshift mirror?

Note:

I can also wget the file from the location that fails in the script.

Yeah quite strange indeed.

Looking at it closely, the script is failing here. The script is doing a curl --head to see if the file is downloadable.

Can you try doing a head to see if that is working?

curl -qs --head --fail https://mirror.openshift.com/pub/openshift-v4/clients/ocp/stable/

You should see something like this:

# curl -qs --head --fail https://mirror.openshift.com/pub/openshift-v4/clients/ocp/stable/

Sorry I should have added that curl seems to work fine as well.

I'm in the same situation. some help please

kxr commented 2 years ago

Let's remove the redirector so we see exactly what error curl is throwing. Can you change the line here from:

            timeout 10 curl -qs --head --fail "${url}" &> /dev/null && ok || err "${url} not reachable"

to:

            timeout 10 curl -qs --head --fail "${url}" && ok || err "${url} not reachable"

and try again.

jma1975 commented 2 years ago

With that modification in the script, it works fine. Thanks !!

juhler64 commented 2 years ago

I'll give it a try. Thanks!

juhler64 commented 2 years ago

Yes this worked for me as well. Thanks.
