Merhaba,
uniGUI uygulamalarında websocket sunucu tarafından web istemcilerine doğrudan mesaj göndermek için kullanılır.
Siz hangi uca (sunucu, web istemcisi) veri yollamak istiyorsunuz?
What will be the usage for this function?
In a single application a function can return this value easily because websockets server is embedded in the application, but in a cluster only the actual WebSockets server knows this number.
Your configuration seems to be correct unless there's something related to your network which prevents communication or some sort of anti virus software which blocks ports or maybe a firewall issue.
Is your private key sent to you by your SSL provider? I am asking this because if you create your CSR (Certificate Signing Request) file yourself, the key file will be on your PC and it will be protected by a password given during creating the CSR.
Yes, I checked the linked you posted and indeed nginx doesn't like underscores in header field names. We will change it in next build to something else.
