I'm trying to set my first c-lightning node with docker-compose using image from https://hub.docker.com/r/elementsproject/lightningd. currently, my node can connect and open channel with other nodes (and I can open a channel to the node just fine), but it's still not updated (ie has no information) on most explorers.

the following is result of getinfo and listconfigs

getinfo

is there something wrong with this configuration? or is it another issue?

I understand that explorers update their node list irregularly, and as far as the node can open channels (and can be connected), everything is fine. but this thing has bugging me for weeks.
