Custom Network is not working

[AndyPuppyZ]

Hello, I’m trying to launch exchange on the xDai network. I tried different things but all of them didn’t work.

I changed the network ID to 100 in the build.ts file then built it then : node ./lib/index.js.
On the wizard I choose custom network then inputed the xDAI rpc address.
.....

when I open the frontend, it gives me a blank page. (I changed the network ID of mainnet to random number and it gave the same blank page)

Can you please help me or guide me how to connect it to Custom network like xDai and Binance chain.
