Can't get messages from server A in server B using LeafNodes

[Thales Maia]

Hi there,

I need some help with NATS leaf nodes and JetStream. Here’s my setup:

1. Local Setup (Working):

   • Two local servers (nats-red and nats-blue) connected to NGS.

   • I can publish in nats-red and subscribe in nats-blue (both with and without JetStream).

2. VPS Setup (Not Working):

   • Deployed a new server (natsmycity) on a VPS with JetStream enabled.

   • Created a stream:

     nats stream add my-stream --subjects "my-subject" --storage file --retention limits --max-msgs=-1 --max-bytes=-1 --max-age=1y --discard old -s nats://user:password@localhost:4222 --domain=br_mg_mycity

   • Publishing messages to my-subject:

     while true; do nats pub -s nats://user:password@localhost:4222 my-subject "Hello from natsmycity with JetStream" --domain=br_mg_mycity; sleep 1; done;

   • Issue: When I try to subscribe to my-subject on nats-red, I don’t see any messages:

     nats sub -s localhost:4223 my-subject

3. Configurations:

   • natsmycity (VPS):

     port: 4222  
     http: 8222  
     server_name: natsmycity  
     jetstream {  
         max_mem: 2G  
         store_dir: "/data"  
         max_file: 5Gi  
         unique_tag: "br_mg_mycity"  
         domain: "br_mg_mycity"  
     }  
     leafnodes {  
         remotes = [  
             {  
                 url: "tls://connect.ngs.global:7422"  
                 credentials: "/etc/nats/NGS-Default-blue.creds"  
             }  
         ]  
     } 
     

   • nats-red (Local):

     port: 4223  
     http: 8222  
     jetstream {  
         max_mem: 2G  
         store_dir: "/data"  
         max_file: 5Gi  
         domain: "debian"  
     }  
     leafnodes {  
         remotes = [  
             {  
                 url: "tls://connect.ngs.global:7422"  
                 credentials: "/etc/nats/NGS-Default-red.creds"  
             }  
         ]  
     }

4. What I’ve Tried:

   • Verified that both servers are connected to NGS.

   • Confirmed that the stream is created and messages are being published.

   • Checked NATS logs for errors (none found).

5. Question:

   • Why aren’t messages published on natsmycity appearing in nats-red?

   • Am I missing something obvious in the configuration?

Any help would be greatly appreciated!
