HTTP Task - Troubleshooting

The underlying connection was closed: An unexpected error occurred on a send

You may receive this error, followed by

'Authentication failed because the remote party has closed the transport stream.'

Your website / external system uses a certain version of SSL or TLS; support for this can be enabled using Zynk's (Advanced) Options, via the Tools Menu

The remote server returned an error: (502) Bad Gateway.

Usually this is an issue with a web-server, eg when posting data.
If the issue occurs on every run this may need raising with the support provider of the server.

This may also be caused by the data, or the volume of data, and reducing the amount of input may resolve.
