Hello everyone, I have an RKE2 Cluster with a topology like this:
A record domain => IP Public => Metallb => Kong Ingress Controller => Service
While I use Cloudflare as DNS and CDN the application runs properly, but when I tried to put the A record without Cloudflare and the SSL termination using Kong Ingress Controller my service does not works properly same as when I use Cloudflare?
But in the browser, I also can access the service. I’ve tried nslookup and curl then my subdomain shows the A record correctly according to the public IP that I have but when I tried to make a CRUD operation to my service and then it did not work properly like the login operation.
What’s wrong with my service and topology? Thank you for your answer
