SSL error using node 17+

[vincentsels]

Describe the bug
All requests result in the following error:

C:\Projects\ext\translate-doc\node_modules\deepl-node\dist\client.js:163
            const error = new errors_1.ConnectionError(`Connection failure: ${message}`);
                          ^

The underlying issue is probably the following: https://stackoverflow.com/questions/74324019/allow-legacy-renegotiation-for-nodejs

This only occurs on Node 17+.

To Reproduce

1. Install node 18 (possibly using nvm)
2. Create a new basic npm project npm init with index.js
3. npm install deepl-node
4. Copy/paste the contents of the 'hello world' example
5. Enter authKey
6. node index.js
7. Generates the above error.

Expected behavior
The translation is logged to the console

Desktop

• OS: Windows
• Node 18.16.1

Hi @vincentsels , thanks for your detailed report.
What is the version of OpenSSL you are using? Is it possible to update it? Are you behind a proxy/in a VPN or something similar?

[vincentsels]

Indeed, it was the company's AnyConnect VPN (or firewall)...

[JanEbbing]

Is the issue resolved then, or do you need to get it to work within the VPN?

[vincentsels]

In my case I can just switch off the VPN while working on this project, so I'll close! I don't suppose there's an easy way to solve it generically for all VPN types / firewalls / ...
