I tried checking in metamask. It is connecting. Please use the following details:
Network Name: Dithereum Testnet
New RPC URL: https://node-testnet.dithereum.io
Chain ID: 34
Currency Symbol: DTH
Block Explorer URL: https://testnet.dthscan.io
If you need Testnet DTH coins, or have any questions, please let us know.
Many thanks.
