CertManager with LetsEncrypt

[MaxThom]

Hey everyone,
I am trying to deploy Nats on Kubernetes with a Public Certificate using cert-manager and lets encrypt. I struggle to pass the HTTP01 Challenge. I use GoDaddy for my records. I found a few solutions for it, but they all seem soso to me:

• using DNS01 challenge, but struggle to configure with GoDaddy
• putting Nats behind a reverse proxy (nginx) so we can have the challenge on http and nats on port 4222, but for me it seems like a bad idea to put Nats behind a reverse proxy, like it would slow down traffic

Any idea or solution? (edited)
