Hi,  
I've run into a problem which I hope someone can help me with. I'm suddenly getting an error on a HTTP node that is POSTing to another server. The flow has been perfectly for almost a year and now suddenly I'm getting the following error:  
"TypeError: First argument should be a valid curve name".

I copied the flow to another machine and on the second machine it works perfectly.

Any guidance will be appreciated
