TLDR: Wilcard subdomain seems to be supported since 24c8a9e971, but it only works for * and not *.multiple.subdomains (It's seems to be related to this resolved issue)

Is this urgent: No
DNS provider(s) you use: Cloudflare
Program version: e19cabc
What are you using to run the container: docker-compose
Extra information (optional)

We could probably fix this small issue by changing a couple of lines in this file
1705afeada/internal/settings/utils/domain.go (L7-L8)

I'll look into it tomorrow. The file you pointed is just for the display in the UI. It should be more inside internal/settings/providers/Cloudflare I think.

Thanks for pointing the issue out!

This should be fixed in the latest image with commit bb62a9d9e1

Actually that was a wildcard bug for many (if not all) DNS providers, so kudos on finding that bug 👍
Also display should now show any.host.host.domain.com for *.host.host.domain.com instead of just any.domain.com which was wrong too.

Let me know if it works for you, thanks!

Hi @qdm12, I tried it with the latest tag from docker hub and it seems to be working ! Here are the logs :
