Issue with Tron sync

[dw-kodani]

In values.yaml, it is defined as follows.

#
# TRON
#
tron_fullnode:
  enabled: false
  url: http://fullnode.tron.shkeeper.io

trx:
  enabled: true
usdt:
  enabled: true
usdc:
  enabled: true

But, all TRC tokens have an increasing number of blocks that cannot be fully synced, as in "Sync In Progress (8117 blocks behind)".

Is http://fullnode.tron.shkeeper.io not a public node? Or does it keep increasing if there are network bandwidth problems?
