Can’t connect to Bitcoind remotely

I am running a Bitcoin Cash node on my server, and starting it like this:

start bitcoind.exe --server=1 --rpcuser=user --rpcpassword=password --rest=1 --rpcport=8332 --datadir=F:Bitcoin --bind=10.1.0.4 --testnet=1 --rpcallowip=0.0.0.0/0

The node runs, and I can connect to it locally.

However, I can’t connect to it remotely, from my C# application, using the BitcoinLib library:

ICoinService coinService = new BitcoinService(ConfigurationManager.AppSettings["Bitcoin_DaemonUrl"], ConfigurationManager.AppSettings["Bitcoin_RpcUsername"],
ConfigurationManager.AppSettings["Bitcoin_RpcPassword"], ConfigurationManager.AppSettings["WalletPassword"]);

I am getting this error:

BitcoinLib: There was a problem sending the request to the wallet.
System: Unable to connect to the remote server.

I have created inbound/outbound rules in the server’s firewall settings, allowing access to the 8332 port, and I think that --rpcallowip=0.0.0.0/0 should allow all IPs to connect to my node… So I really don’t know what the problem is.

Edit: I can’t access the node from https://bitnodes.earn.com/ either.

Update: the node has finished reindexing blocks, and I still can’t connect to it remotely.
