Can't connect to server. Error message: Not Found

[peder]

Can you ping the server reliably? Because it kind of seems like it's a network problem.

Start a CMD prompt on your XCP-ng Center PC and run ping -n 30 192.168.66.17 to see if you get packet losses.
If you do then it's probably a bad NIC or cable or switch port.

@peder - yes no packet losses when running ping -n 30 192.168.66.17.

Are you sure you are pinging the right machine? No change you have a duplicate IP address?

[runevn]

@jedimarcus - yes I think so. I'm pining the management interface, which is the right interface to ping right?

I really don't think that I have another machie running on that IP. 192.168.66.17 is out of the DHCP servers scope. And when I enter the IP in the browser I'm shown the welcome to XCP-ng screen where I have the option to install XOA or download the XCP-ng Center app.

Isn't there a password field you must type in when connecting XO to a new host? Are you supplying it with a password?

Its been a long time since I setup a new host so perhaps I'm wrong.

[runevn]

@Biggen Yes, I have checked that box/slider. But no luck.

I tried to ssh into the XCP-ng server, which worked fine I ran some commands but then the connection got closed (Broken pipe) with the argument that the remote host identification has changed.

Host key verification failed.

This fingerprint key is different from what I can see when I go under "Status Display" on the XCP-ng server.

I don't know if this helps but it seems that I have some issues with authentication both on the XCP-ng Center, XO and when I SSH into the host?

Any idea of what I could do? And please let me know if you need more information.

Thanks

This usually means you have another machine on this IP.

[runevn]

Wow - you guys where right. I had a Raspberry pi running with that address on my network. Sorry for the inconvenience and thanks for your help.

No worries, if we knew the answer it means we made the mistake ourselves in the past.
