Error Transferring data: SSL peer certificate or SSH remote key was not OK

[KB1]

Hi,

My download workflow had been working fine for more than one year and suddenly stopped working and gave me this error message (and it is not due to my id/password because I can perform the same download function manually).  

"Error Transferring data: SSL peer certificate or SSH remote key was not OK"

Has anyone else experienced the issue? If so, what was reason of this error and how did you fix it? Thanks for any help!

@KB1This community post might help.

The issue here is whether the computer trusts the certificate. If the computer doesn't trust the certificate then Alteryx will error. Establish a valid trust with the signing authority for the problem certificates. Are yours self-signed or are they signed by an internal certificate authority? 

Since the Download tool uses libcurl to automatically verify the peer, there is a flag that you can use to disable it using cURL. You'd use the Run Command tool in your workflow, including the command/ parameter.  There is a good article on the Community that includes a similar cURL example: 
http://community.alteryx.com/t5/Alteryx-Knowledge-Base/The-Run-Command-Write-Source-amp-Read-Results...  Another helpful resource: https://curl.haxx.se/docs/sslcerts.html.

If the certificate is self-signed, you could copy the self-signed certificate to the workstation that Designer is running if you don't want to use curl. 

There are two solutions:

1. Get a valid SSL certificate.
2. Disable SSL verification in Curl. (add --insecure option)

Thanks DiganP. I'll try to get the new certificate.

Can I get the exact steps for #2 ?

How can we add --insure in Alteryx? No one posts that.

Have you found an answer?

@npandya - You can't in the Download tool. You can in the Run Command tool. This post explains more:

Where can I change to accept https without a certificate (insecure option) in the download tool??

I had the same issue and as a temporary workaround, I installed 2021 version (the workflow was originally designed in 2021) and it runs without any issues.

I believe the newer versions (2023,2024) have better authentication protocols which use secure connection - which was causing the issue.

I will eventually move back to 2024 after figuring out a way to run the insecure option within the download tool.
