Ganache RPC Server Issue - Information

[alymurtazamemon]

Before reaching this point, I saw many people were facing the issue with Ganache while deploying the smart contract. I personally face this issue now and the simple solution to that issue was to change the Ganache RPC Server endpoint.

Follow these steps, if you face the problem;

1. Inside Ganache in the top-right corner tap on the gear icon (settings).
2. Then in the server tab, change the HOSTNAME and select 0.0.0.0 - All Interfaces.
3. Now replace your RPC Server URL inside the code with this latest URL that will be something like: HTTP://0.0.0.0.7545. Recheck this from Ganache.

I hope now you will not face the issue like me!

For me: I had to change it to 192.x.xxx, port 8545, chainId: 1337

If its not working
Try going to settings, then server and changing it to Hostname: 192.xxx.x.xxx, Port numer: 8545, and chain id: 1337

Then using that info for your metamask.

If your metamask cant connect to it, your contract probably cant ether.

You don't really need to use ganache with hardhat. It has a built in backend.

any changes related to chainId or will any chainId work?

[heysourin]

Didn't work for me. I had to change the server to http://192.168.0.147 -WiFi, then only it worked. Can anyone explain what happened here?
