Failure Unable to get endpoint type

After installation of a k3s cluster, I installed portainer agent (as described https://www.portainer.io/installation/), I am trying to connect via port 9000.
I also tried via node port 30777, every time I get the error: Failure Unable to get endpoint type.

What exactly does that error mean?
How can I solve it? what should I look for?

I have remote connected multiple times before - but up against docker - not k8s

Hi
please refer this page on documentation and let us know if it helps

Hello,

That did the trick. That was great! Thank you!
What went wrong on the way, I cant tell for certain, but a mismatch of old documentation - eg. it says on your webpage it uses port 9000, then on retry I forgot to open the right ports after resetting the servers etc.

  • If I might suggest something. It would be nice to have the most basic - simple -checklist in the documentation, like what ports must be opened in the firewall. (for dummies like me) - I often do that mistake when learning new stuff, I overlook the most basic. And I learned - that you can never tell, what information expected implicit, or what is “missing”

If it seems like a good idea to you I´d be happy to contribute with that.

Edit: of course I am behind a load-balancer, just havn´t set one up manually.
