user6763: when starting the testnet node using
cardano-node run +RTS -N -A16m -qg -qb -RTS \
 --topology testnet-topology.json \
 --database-path testnet/node/db \
 --socket-path node/db/socket \
 --config testnet/node/config_files/testnet-config.json

the server starts correctly, but fails connecting to the peers (in order to sync)
my testnet-topology.json looks like this:
{
  "Producers": [
    {
      "addr": "relays-new.cardano-testnet.iohkdev.io",
      "port": 3001,
      "valency": 2
    }
  ]
}

which is the default one
the error I receive is the following
Domain: "relays-new.cardano-testnet.iohkdev.io" Connection Attempt Exception,
destination [<probably iohk ip but omitting anyway (ipv6)>]:3001
exception: Network.Socket.connect: <socket: 50>: does not exist (Network is unreachable)

and after a while
Domain: "relays-new.cardano-testnet.iohkdev.io" Application Exception: <some ipv4>:3001
MuxError (MuxIOException Network.Socket.recvBuf: 
resource vanished (Connection reset by peer)) "(recv errored)"

so I assume the problem is in the topology.
is the topology wrong? if yes can you provide the right one?
is the node version a problem due to Vasil?

user5926: You must be running node@1.35.3 to correctly interact with the post Vasil HF chain.

user6001: AFAIK 1.35.X is needed for Vasil.

Edit: Just for clarification, Becky from IOG posted on Discord today
"Please note that we are deprecating node versions 1.35.0 and 1.35.1 . These contain known issues and should not be used. SPOs wishing to test Vasil functions ON THE TESTNET ONLY should do so using node version 1.35.2. SPOs should continue to run 1.34.x on mainnet until an official mainnet release is confirmed."
