Hello I have a VERY WEIRD problem with ssh connection to different Raspberry Pi running dietpi headless and serial connection not enabled
=> Network error connection refused
I'm running the latest Dietpi version V6.25
I have 3 Raspberry Pi (1x Rpi 3b+ and 2x Rpi 3a+)
I have 3 Windows PC (2 Windows 10, 1 Windows 8)
I have 2 Router
I just installed fresh version of Diepi (headless) AND COULD CONNECT THROUGH SSH to it during the software installation process
At the end of the software install, I made a reboot and then I got the "Network error connection refused"
I tried again, a new fress install on a second Rpi 3a+ and got exactly the same issue.
I plugged in an other Rpi 3b+ with its own SD (that was still working yesterday), and got exactly the same issue, impossible to connect anymore !
In each case I see the Rpi IP address with IP scanner (Fing Overlook) and on the latest Rpi 3b+ I can still access the hosted logitech media server web page...
What I tried to solve that issue:
I erased the cache from my putty on one Windows PC,
I tried Putty access from another Windows PC,
I Switched off and restarted my regular internet router, no way !
I tried another router, not connected to Internet and that none of the peripherals had ever been connected to, but still I got the Network error connection refused, although I got the IP address of each peripherals.
In other words, I can't access anymore my long time running setup and/or I can't install new setups
Do you have any hints to recover the connection and most important to avoid this problem in the future ?
