Hi Shabaz
Since I can’t check my configuration anymore as I don’t work anymore for this project, it’s a little bit difficult to answer. What i remember is that you have to configure this file : chirpstack-fuota-server/chirpstack-fuota-server.toml at master · brocaar/chirpstack-fuota-server · GitHub to with your application server ip and token (to communicate from FUOTA Server to application server)
From the application server to the FUOTA Server it’s correct as you did, but I’m not sure about the 8070/up. I think it should also correspond to the chirpstack-fuota-server.toml definition
Sorry that I cannot help more. It would be great to have a bit more documentation for this feature, it’s not so easy to understand…
