Unable to find any RPC peers

Question

I set up an RPC node following the suggestions on the official docs, the launch script looks like this.

#!/bin/bash
export RUST_BACKTRACE=1
export RUST_LOG=solana=info
exec solana-validator \
  --identity /home/solana/.config/solana/id.json \
  --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 \
  --known-validator 5D1fNXzvv5NjV1ysLjirC4WY92RNsVH18vjmcszZd8on \

  --enable-rpc-bigtable-ledger-storage \
  --no-duplicate-instance-check \
  --wal-recovery-mode skip_any_corrupted_record \
  --log /home/solana/.logs/rpc-node \

  --rpc-send-default-max-retries 30 \
  --rpc-send-service-max-retries 30 \
  --rpc-send-retry-ms 2000 \
  --full-rpc-api

I noticed after I perform a restart the process spends a lot of time (several minutes) stuck on this message

[2024-10-21T15:36:14.912202575Z INFO solana_validator::bootstrap] Searching for an RPC service with shred version 50093 (Retrying: Wait for known rpc peers)...

[2024-10-21T15:36:14.912418814Z INFO solana_validator::bootstrap] Total 0 RPC nodes found. 0 known, 0 blacklisted

In some cases, I even get this error

[2024-10-21T15:38:26.313727162Z ERROR solana_validator::bootstrap] Failed to get RPC nodes: Unable to find any RPC peers. Consider checking system clock, removing --no-port-check, or adjusting --known-validator ... arguments as applicable

Googling around, it seems this can be improved by changing the list of known-validators, however I am using those suggested in the official docs so I would assume they're some of the best. Also, I tried changing for some others but the result is unchanged, the node still spends a lot of time waiting to find a suitable RPC node. Does this have anything to do with my configuration? I might be wrong, but I assume the time spent searching for nodes is time my own node is not actually receiving time, so the data will be delayed. Because I am going to use this node to receive real time block data, that would be a problem.
