Network & RPC Issues
How to Fix a MetaMask RPC Error
Learn what RPC errors mean in MetaMask and how to troubleshoot them safely.
Quick answer
What this usually means
RPC errors usually mean the wallet cannot communicate correctly with the selected network endpoint.
Common causes
Why it happens
- The RPC endpoint is down or overloaded.
- The network configuration is incorrect.
- The dApp request is malformed or unsupported.
- The wallet cache or session is stale.
- The chain is congested or temporarily unstable.
Fix path
What to check first
- Refresh the dApp and wallet.
- Switch to a trusted RPC endpoint.
- Check the chain ID and network settings.
- Try another browser profile if the issue persists.
- Avoid signing repeated failed prompts.
Safety note
Do not make the problem worse
- Do not add RPC endpoints from random messages.
- Incorrect RPC can mislead wallet displays.
- Official network documentation is safer than social comments.
