More likely the other party made a mistake. Like surely was the case in the other topic.
Ah, if you can change the gateway ID then, yes, that would be an easy solution. See DevEUI for non-hardware assigned values - #23 by terrillmoore.
(Aside: your EUI is indeed assigned to Dragino, not to RAK.)
That, by the way, is not true. EUIs are not random, but are taken from a range assigned to (purchased by) some manufacturer. In the factory, they’re probably assigned to products sequentially. So, if a user makes a tiny error, then chances are good that it ends up being an EUI assigned to another piece of hardware in the same product range.
So:
…is not a good idea, and is assigned to Dragino. (Though not known to TTN, yet?)
The good thing: in the other topic we learned that deleting a gateway (usually) does release its EUI, despite the alarming warning. So, if someone realizes their typing mistake, all is probably fine if they then delete the gateway from TTN Console.
Hello!
I accidentally deleted my gateway like everyone else here. My gateway EUI is 24E124FFFEF12023. Mac address is 24:e1:24:f1:20:24. Could you please delete my gateway so I can register it again? Sorry for all the trouble I’m giving.
Thank You,
Firat.
If you read the thread above you’ll see that this is not possible.
Can you tell us the make and model of the gateway so we can figure out if the EUI on it can be changed.
The gateway is Ursalink UG-65. Sorry for the trouble I’m giving.
And what does the documentation for that gateway say about the EUI?
It says that it cannot be changed.
And what does it say underneath that bit?
This is all the information provided in the user manual.
Read the whole block - the answer is there.
But to save all our sanity, scroll down …
It says the id you register on a network server, such as TTN … … can be changed.
Thank you for your help, again, but I decided to write in this thread upon trying to connect and failing after registering the ID I’ve changed like you’ve suggested.
I think you’re telling me you tried to register with a different EUI from the original one?
Is there anything else you tried? So we can save time suggesting other remedies.
So you need to figure out an EUI that you can use - hopefully someone who knows more about generating an appropriate EUI will come along shortly.
Or look at this for EUI generation:
It is common for the EUI to be generated by adding FFFF or FFFE in the middle order bytes of the primary (usually Wireline) ENet MAC, or for WiFi only devices like the TTIG, the WiFiMAC.
In your case I note from original post:
And it looks like they dont match or you have another typo!
Can you post back and confirm the MAC and what EUI has been set for the GW (Not what has been entered by you in console…)
I simply took my MAC address, formed it into an EUI (inserted FF and FE in the middle) and changed my Gateway ID as so. But my gateway EUI did not change. But still, I went ahead and typed in my new Gateway ID as Gateway EUI. It does not connect.
I tried to access my gateway through SSH, but it won’t give me permission to do so.
So what EUI have you registered in TTN Console - the one ending 23 or one derived from the MAC ending in 24?.. or something different…
Hello! I know they don’t match. I would like to write down my steps:
1- Deleted the registered gateway accidentally.
2- After seeing my mac address, i changed my gateway id to 24E124FFFEF12024.
3- Registered another gateway with EUI 24E124FFFEF12024.
But it won’t work. 
That shows Registered GW (vs ID) as ending '23…can you condfirm the EUI of the Actual GW NOT the TTN Console registration, please. It may be that you have another problem where TTN Console doesnt show reliably the connection status. Do you have a node registered and App running - can you see any data?
Checking the NOC I can see a '23 GW breifly connected on 13th Jan - I guess yours before deletion?
No GW derived form a MAC ending '24 registered… 
I might have misunderstood you, but if you want me to confirm if my gateway ID and registered gateway EUI do match, here I can send you two photos.
I had just updated my last post when you put up the pics. I see no '24 EUI registered through the NOC as you can see. Can you confirm what you deleted in the Console - a '23 or a '24 based registration?
