Those are OPenLedger api nodes, either contact their support or try another api node

Why now dont work rpc calls?
For example:
curl --data '{"jsonrpc": "2.0", "method": "get_account_history", "params": ["customminer", "1000"], "id": 1}' bitshares.openledger.info/ws

or:
curl --silent --data '{"jsonrpc": "2.0", "id":1, "method":"get_order_book", "params":["USD","OPEN.ETH",2]}' https://bitshares.openledger.info/ws

all works 5-6 month ago.
now return 403 Forbidden
