Mjml: local issuer certificate error when using mjml api

[landoephan]

I use the API since a few weeks and everything worked fine, but today I suddenly ran into this error when trying to send mails:

requests.exceptions.SSLError: HTTPSConnectionPool(host='api.mjml.io', port=443): Max retries exceeded with url: /v1/render (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1123)')))

I didn't change my config or anything. I also tried to retrieve new API Credentials, but I didn't receive a new email so far.

Having the exact same issue.

Same here, there seems to be a certificate problem on MJML end

Having the same issue in https://github.com/Automattic/newspack-newsletters. As of a few hours ago the MJML API started returning {"errors":{"http_request_failed":["cURL error 60: SSL certificate problem: unable to get local issuer certificate"]},"error_data":[]}

Hi everyone, sorry about that. We've identified the issue and working on a fix. There is a valid certificate on mjml.io but the issue is related to the intermediate chain.

[landoephan]

issue seems solved

[ngarnier]

Yes, we just put a fix in place. Sorry for the issue and feel free to report if you see anything else.

Hi,

The problem seems to be back :(

SSL certificate problem: unable to get local issuer certificate (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

Thank you

The issue is back .. Any suggestion?

[landoephan]

how should one use mjml api in production if it's not reliable?

For people using the API in PHP software you could "solve" by installing mjml cli.

Run this :

npm install -g mjml

Then in your code you can make something like this :

    $input_file     = "/tmp/".time()."_input.mjml";
    $output_file    = "/tmp/".time()."_output.mjml";

    file_put_contents($input_file, $mjml);

    $res = exec("mjml {$input_file} -o {$output_file}", $error, $return_var);

    // print_r($res);
    // print_r($error);
    // print_r($return_var);

    $html = file_get_contents($output_file);   

    unlink($input_file);
    unlink($output_file);
