MetaMask is a popular Ethereum wallet and browser extension that allows users to interact with decentralized applications (dApps) on the Ethereum blockchain.
While MetaMask provides a seamless experience for most users, encountering errors like the “Internal JSON-RPC Error” can be frustrating and disrupt the user’s interaction with dApps.
The common error message displayed is: “Internal JSON-RPC error.”
In this article, we will explore the causes behind this error and provide potential solutions to fix it.
What Causes “Internal JSON-RPC Error” On MetaMask
Internal JSON-RPC Error is an error that arises when there is a communication issue between two computer programs utilizing the JSON-RPC protocol.
JSON-RPC serves as the mechanism for one program to send a request to another program and obtain a response.
The occurrence of an internal error suggests that something has gone awry within one of the programs during this communication process.
This could be attributed to a bug in the code, misconfigured settings, or other obstacles hindering proper communication between the two programs.
Although the error message typically provides some insight into the problem, comprehending and resolving it without technical expertise can be challenging.
