rpc node can't catchup

[jzqgx555]

I'm new in solana and I wanna build my own rpc node
this is my solana-validator.sh

`solana-validator
--ledger ~/ledger
--accounts ~/accounts
--identity ~/validator-keypair.json
--known-validator 7Np41oeYqPefeNQEHSv1UDhYrehxin3NStELsSKCT4K2
--known-validator GdnSyH3YtwcxFvQrVVJMm1JhTS4QVX7MFsX56uJLUfiZ
--known-validator DE1bawNcRJB9rVm3buyMVfr8mBEoyyu73NBovf2oXJsJ
--known-validator CakcnaRDHka2gXyfbEd2d3xsvkJkqsLw2akB3zsN1D2S
--expected-genesis-hash 5eykt4UsFv8P8NJdTREpY1vzqKqZKvdpKuc147dw2N9d
--entrypoint entrypoint.mainnet-beta.solana.com:8001
--entrypoint entrypoint2.mainnet-beta.solana.com:8001
--entrypoint entrypoint3.mainnet-beta.solana.com:8001
--entrypoint entrypoint4.mainnet-beta.solana.com:8001
--entrypoint entrypoint5.mainnet-beta.solana.com:8001
--rpc-port 8899
--dynamic-port-range 8000-8020
--wal-recovery-mode skip_any_corrupted_record
--init-complete-file ~init-completed
--limit-ledger-size 50000000
--log ~/sol-log
--only-known-rpc
--full-rpc-api
--no-voting \

    --enable-cpi-and-log-storage
    --no-snapshot-fetch`

And then I can see snapshot downloading in log
like:
root@free:~# tail log
[2024-05-13T08:30:34.585291825Z INFO solana_download_utils] downloaded 13457136648 bytes 18.0% 48295728.0 bytes/s

after the download my rpc node will show me something likc this:
and when I check with solana catchup it shows :

solana catchup --our-localhost --url https://solana-mainnet.g.alchemy.com/v2/xxxxxxxxxxxx
⠓ 24708 slot(s) behind (us:265470517 them:265495225), our node is falling behind at -2.2 slots/second (AVG: -2.5 slots/second (falling))

In log there are many timedout reports

I try to telnet 208.85.23.4 11228 it shows :
root@free:~# telnet 208.85.23.4 11228
Trying 208.85.23.4...
telnet: Unable to connect to remote host: Connection refused
why my rpc node connected 208.85.23.4 at 11228 port

I thought maybe the Gbps is not enough or cpu or memory is not enough ,but it seems ok
when the snapshot's downloading was finsh, starting lag
please tell my what can I do to fix this problem
