One of my home server suddenly wont let me access an ssh share. It was working fine 2 days ago. I tried to test this by recreating a share on Ubuntu with PLDT as my ISP (as well as windows with different Globe ISP) but both shows the same Connection Refused error as shown below.
It looks like the connection to your ssh server happens successfully over zrok, but then your host rejects ("refuses") the connection. Are you able to connect directly to your ssh server outside of zrok? There are a number of posts on stackoverflow that give some advice on troubleshooting kex_exchange_identification: Connection closed by remote host (e.g., ssl - kex_exchange_identification: Connection closed by remote host - Stack Overflow) that might be helpful.
The device named "LOQ" where you ran zrok share private -b tcpTunnel 127.0.0.1:22 displays an error:
TCP 127.0.0.1:22: connect: connection refused
This means the SSH server is unavailable at the address 127.0.0.1:22. You must share a TCP address that LOQ can reach without zrok. Then, you can reach the SSH server from another device by running zrok access private.
