Weird URLConnection problem

General
1

Here is a problem I can’t seem to be able to pin-point. There have been no changes made to the code for over a year, but it stopped working after I compiled it with Xojo 2025r1 and newer, it seems.

The following code does not send an e-mail to Resend when I run it, neither using SendSync or Sync.

However, if I debug it and step through the code, it works fine. Why is SendSync failing?

URLServer.Disconnect

// Set header
URLServer.ClearRequestHeaders
URLServer.RequestHeader("Authorization") = "Bearer "  + K_RESEND_APIKEY

// Assemble the content header
Var oJSON As new JSONItem 
oJSON.Value("from") = "noreply@eldr.is"
oJSON.Value("to") = Email.Lowercase.Trim
oJSON.Value("subject") = Subject
oJSON.Value("html") = HTMLBody

// Set the JSON as request content
URLServer.SetRequestContent(oJSON.ToString,K_APPJSON)

// Send the request
return UrlServer.SendSync("POST","https://api.resend.com/emails",10)

From the docs:

Disconnect

Disconnects the socket.

A disconnected socket is not set to Nil, but is no longer in a useful state. You should create a new socket rather than attempting to re-use a disconnected socket.

Can you try creating a new URLConnection instead of using disconnect?

That solved it! But this worked all this time (years) but changed with 2025r1!

Anyways, thanx mate
