Two nodes on different public IP, but same identity keys

I currently have two nodes on different public IP, but same identity keys.
NodeIDs turned out the same - 12bTb4hXRQrA9W5CaMmAmG8bS2M8oBnBcBq3E9q5pQB5jaHTYsu
Is it right?
The last five days nodes status OK, but not receiving any data.
Nodes are running on version v0.15.3.

Hey @Anderstad welcome to the forums!

You should only be running one node per identity key. You will get DQ’d running it like that.

This is a fastest way to disqualification. Each of your server will have only part of the data and fail audits for other, which is on other server right now and vice versa.
Of course, it’s already disqualified for too many failed audits.
