No Peers - Mainnet

[azgms]

Hi guys, have my node bootstrapped and configured as shown in docs, but its struggling to get peers either way.
Running version v2.4.2 and these are my init flags

XDC-$NETWORK
--datadir /database
--XDCx.datadir /database/XDCx
--networkid 50
--etherbase "0x0000000000000000000000000000000000abcdef"
--nat extip:$EXTERNAL_IP
--port $EXTERNAL_PORT_0
--syncmode full
--gcmode archive
--verbosity 3
--rpc
--rpcaddr '0.0.0.0'
--rpcport 8545
--rpccorsdomain ''
--rpcapi 'web3,eth,txpool,net,debug'
--rpcvhosts=''
--ws
--wsaddr '0.0.0.0'
--wsport 8546
--wsorigins '*'
--wsapi 'web3,eth,txpool,net,debug'
--rpc-gascap=0
--rpc.txfeecap=0
--slave
--bootnodes "$bootnodes"
--metrics
--metrics
--metrics.addr=0.0.0.0
-vvv

Any help would be appreciated, thanks!
