A couple of days ago I bought a new raspberry pi 4, for now, I don't have desktop support but I set it up in headless mode (installed raspbian on sd card).
I was able to connect it using ssh when it was using my old router (192.168.1.xx was my pi's address) now I am using a different network(192.168.43.xx) which is a mobile hotspot and I can't connect to ssh, nmap shows that all ports are filtered (-Pn)
fortunately, I had tor hidden service set up and I am able to connect to the onion address, but this is not comfortable at all
is there anyone who had a similar issue? and what would be a solution
