Posting here to get opinions on how secure this server set up is

I have Cloud Flared tunnels set up for 3 sub domains with https

https://chat.my-domain.net (Mattermost)

https://kwix.my-domain.net (Kwix)

https://nextcloud.my-domain.net (Nextcloud)

All hosted on one machine with 64 gb ram and 12 core processor. Each service is running in docker. The corresponding port is exposed on in Ubuntu firewall and on my home router.

Other than the memory consumption of running 3 separate tunnels along with the apps, is there any other concerns with this set up?
