Hello friends,
I am slowly despairing. I’ve been active on HTB Academy for over 6 months and have never had any problems with ssh connecting to the labs. I use my own Attacker machine.
For a few days, however, I can no longer connect to a service on the HTB using ssh. No matter which lab. I always get the answer: Connection closed by HTB_IP port 22. But it works with the HTB Pawn-Virtual-Machine.
I checked the following:
- VPN connection ok
- Trace route ok
- PING ok
- Disable Firewall
- new installed ssh service on linux
Please, if anyone has an idea, I would be very grateful.
