Description

There seems to be an issue when trying to use this with a vpn/proxy. My application run without a problem when off vpn and no proxy env variables. But the second I'm on the vpn I keep on getting ECONNRESET.

When on VPN+proxy I can curl the WSDL url without any issue

Ive tried something like this

  fastify.register(fastifySoapClient, {
    url: 'test?WSDL',
    options: {
        rejectUnauthorized: false,
        forceSoap12Headers: true ,
        wsdl_options: {proxy:{
          protocol: 'corporate protcol', 
          host: 'corporate host',
          port: corporate port,
        }}
    }
  })

Error Output
