Hi @angel.olivares,

Are you running the lab in the cloud or local? If local, can your host reach the VM's network?

Hi, thanks for your replies.
I'm running the nodes in local, i can access thee nodes from the host's terminal and able to curl the cluster ip and endpoints from the cp as in previous steps 3.4.26. curl from host to public ip timed out too

Hi @angel.olivares,

What type of network interface do you have on your VMs, and how do they get assigned public IPs?
What IPs are returned by curl ifconfig.io and curl ifconfig.me? (feel free to mask the last two octets of both IPs)

Regards,

Hi, I've been looking into this and recently run onto the same issue when testing another application. it turns out that my ISP has something called CGNAT activated wich prevents resolving incoming traffic and you can't do things like running a server for example. I have to pay to desactivate this but once done it should work.
