Ethereum: WebSocket handshake declined by remote peer

Ethereum: WEBOCKET hand compression with a remote fur
When building devices, especially Ethereum (ERC-20-token), it is not unusual for you to expose problems with web socket connections, including hand shake. This process is crucial to create real-time communication between customer application (e.g. web interface) and the server or application interface. In this article we deal with why telemariums can reject the handwriting of web socket and give instructions on the problematic error correction and solution to the problem.
What is the website hand compression?
Websocket hand compression is a protocol with which a two-way communication channel is set up online between two parties. It contains several steps:
- Handwriting Start : The customer (e.g. web interface) sends a “website” request to the server.
- Serb confirmation : The server checks the customer’s identity and checks all of the security dates.
- Hand compression negotiations : If the certification is successful, the customer and the server negotiate the website version and the encryption method.
- Connection : If the connection is agreed, the connection is established.
Ethereum Details
When it comes to the hand compression of Ethereum Websocket, several custom steps contain:
- ERC-20-token connection request : If a user starts a website connection to achieve an ERC-20 or an intelligent contract, the customer sends a “website” connection request.
- ERC-20 token certification : The server checks the identity of the user and checks the susceptibility to security connected to ERC-20.
- Hand compression negotiations : If the certification is successful, the customer and the server negotiate with the adapted keys (e.g. X-ECDSA-256`) in the web socket version and the encryption method.
- Connection : If the connection is agreed, the connection is established.
Why is webocket hand compression rejected?
If you encounter problems during the Handshake process, there are several possible reasons for:
* False server certificate
: The server certificate may not match the expected certification criterion of the customer.
* Inadequate trust anchor : The server may not have a trust anchor (e.g. a list of reliable certificates) to check the identity of customers.
* Certification validation error : The process for validating the server certificate can fail, which leads to a reduction in the handshake.
Error removal stages
Follow these steps to solve problems during the website manuscript:
- Make sure that the server certificate : make sure that the server certificate reacts to your expected certification criteria with tools such as OpenSSL or Certbot.
2
- Set the website connection : Check and update the customer application code to ensure the corresponding configurations of the adapted keys used during the Handshake.
Diploma
Creating a reliable website connection to Ethereum requires attention to the details and a thorough understanding of this protocol. If you follow these steps and the failure of the general problems, you should be able to solve the error with the hand compression of web socket hand compression and to determine real-time communication between the customer application and the server or application interface.
Check and update your code regularly to ensure that the development of security standards and best practice in blockchain apps the development of security standards and best practices.
