Unsupported network ${networkId}

[soccerarenadev]

When using a not supported network, I'm getting this error (Unsupported network ${networkId}).
However, it shouldn't be this way.
Instead, on an unsupported network it should just return the main network ENS.

When using a non supported network it should default to mainnet. Doesn't make sense to have a ENS service that only works on mainnet and in different chains have different IDs.
Different networks supports just make sense to testing (testnets).
