Can't add a non-authority node to my private Proof of Authority network in Parity

Question

I followed these instructions and everything works until I try to add a new non-authority node form another machine. (Point 8)

The authority nodes are running on Microsoft Azure and they are connected to each other (0/1/25 peers) and work fine.

I've tried all the commands and suggestions I can find online, but nothing works. I get the enode:// of the authority node and then use the command

curl --data '{"jsonrpc":"2.0","method":"parity_addReservedPeer","params":["enode://RESULT"],"id":0}' -H "Content-Type: application/json" -X POST localhost:8540 

with the correct enode number and i get result "true"

curl --data '{"jsonrpc":"2.0","method":"parity_addReservedPeer","params":["enode://2aba3164aee2b387ed20ca917766728ba36853cd52490787778a9dee4a21167de40c936459e054ee0a6bf462e72864d1ad93d9a3aa288481d222c854d43c0e06@10.0.2.5:30300"],"id":0}' -H "Content-Type: application/json" -X POST localhost:8540
{"jsonrpc":"2.0","result":true,"id":0}

but then the node is not connected to the private network.

Any help would be very appreciated because I've busting my head on this for ages now.

Thanks in advance

From the authority node I get the following:

From the non-authority that i try to add without success, this:
