IPv6 : Unable to show host availability
Bug description
Put here a clear and concise description of what the bug is Hello,
I always get a red flag when connecting to my servers whereas the connection is possible. I don’t if it is a ping or something that may be blocked by the server?
Screenshots
If applicable, add screenshots to help explain your problem
Steps to reproduce
- Try to connect to a server
- Error is thrown
Thanks for your feedback @DorianCoding 🙏
Availability is done yet by checking the SSH port is opened or not. Ping availability checkup is not yet implemented.
Red flag but connecting is possible or not at all? If not : could you post the root cause from the logs?

Yes connection is perfectly possible, this is why I am kinda skeptical as the port is definitely open and there is no port knocking.
OpenSSH_for_Windows_8.1p1, LibreSSL 3.0.2 debug1: Reading configuration data C:\\Users\\FIJITSU/.ssh/config debug1: Connecting to xxxxxx [2a01:xxxxxxxx] port 22. debug1: Connection established.
NB : Is the check done using ipv4 or ipv6? Because I'm connecting using ipv6 and ipv4 "port" is indeed closed. If it is the cause, I guess availability should be done trying both, starting with the preference set.
Thanks @DorianCoding
Any firewall or application filter on the server side?
On your computer (not server side) what about :
nmap -p22 yourhost
If 22 is your port
Good spot @DorianCoding !
You seems right about IPv4/6 I think I'm not doing the good job.
I will fix it so 😉
