So this confirms that DNS is the issue.

Here is what I get when attempting the same test:

$ nslookup 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Server:		172.20.10.1
Address:	172.20.10.1#53

Non-authoritative answer:
Name:	2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Address: 192.168.0.110

So you see, I’m getting the actual resolved address of 192.168.0.110 which is correct.

You can also try the same command using Google DNS server at 8.8.8.8:

$ nslookup 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io 8.8.8.8
Server:		8.8.8.8
Address:	8.8.8.8#53

Non-authoritative answer:
Name:	2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io
Address: 192.168.0.110

So the issue is most likely your router which I assume is at address 192.168.0.1 based on your previous attempts.
The router is probably blocking resolution of the DNS hostname to a local IP address.
You will need to lookup instructions for how to allow a specific hostname (2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io) to be allowed and not blocked.

Thanks. I will do some checking and let you know what I find. You have been most helpful…

When trying to research this for your router, the keyword “DNS REBIND” or “DNS REBINDING” is what this behavior is typically called. It’s a security measure that some routers implement.

Using Google it the lookup works

C:\Users\Paul>nslookup 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io 8.8.8.8
Server: dns.google

The Google lookup worked so that means that your assigned FQDN is valid and publicly resolvable.
However, once you resolved it, it is now cached for a little while on your local system/computer.

The ping is now working because the DNS hostname is now cached on your local machine.
If you go back and try to resolve it again after a while (without the Google DNS server) just using your default DNS servers, it will probably fail to resolve the hostname again.

You can use the following command to force a flush of your local DNS cache (on Windows).

ipconfig /flushdns

I don’t see a way to manually add additional DNS servers to the Alexa Echo device, so the FQDN will need to be resolvable by your router.

Thanks, Robert

You are exactly right; but you knew that. During that short time i was able to see 2 cameras on the spot but not the tablet. I’ll keep working.

Also, some routers will allow you to simply override a DNS host to a fixed address of your choosing. This could also be an option for you if your router allows that. You would just use the hostname 2b49b758-a6fd-4a36-a6ac-29b674ff1ce5.mproxy.io and have it pointed to the gateway’s IP address (192.168.0.110). So instead of the router actually resolving the address from a public DNS record, it just returns the overridden IP locally.
