Unable to establish SSL connection with wget

curl

I am trying to execute :

wget https://app.adroll.com/api/v1/export/all_campaigns_report?advertisable=T4ZPAGYESJEZZMCCBVEMHK&reports=AllCampaignsSummary,AllCampaignsChart,AllAds,AllCampaignsSites&format=csv&currency=USD

I replaced wget 1.12 with 1.16 on my centos machine.

I have set check-certificate option to off in 

vi /etc/wgetrc

I can infact use https usually with wget

wget https://google.com

It doesn't give ssl error with google.com.

Infact I can access the link on browser just fine. Why does it seem to fail with wget then?

With this command, I get:

[root@warehouse ~]# wget 'https://app.adroll.com/api/v1/export/all_campaigns_report?advertisable=T4ZPAGYESJEZZMCCBVEMHK&reports=AllCampaignsSummary,AllCampaignsChart,AllAds,AllCampaignsSites&format=csv&currency=USD'

Edit: Tried with single and double quotes as well.Made no difference:

Edit2: Tried with –no-check-certificate as well:

Best Answer

You can connect to the server, as seen by the line * Connected to app.adroll.com (52.11.56.178) port 443 (#0) (that excludes firewall and/or routing issues) but then the connection gets severed, as indicated by the NSS error code * NSS error -5938 * Closing connection #0 and curl: (35) SSL connect error.

Typically you would need to see the server-side log to know the exact reason, but @Anubioz seems to have the right idea, the server blocks your connect attempt.

You may be running afoul of their invalid traffic protections if you connect from certain IP-address ranges.

"Any domains identified as sources of invalid traffic are permanently blocked."
