hysteria2 cannot establish a connection

[Catcher-u]

I'm using an Oracle vps. After installation hysteria2 works fine, but it does not connect successfully either through a third party client or the official one. Someone please help me with this, thanks.

The server side is working fine. ` ubuntu@instance:~$ sudo systemctl status hysteria-server.service ● hysteria-server.service - Hysteria Server Service (config.yaml) Loaded: loaded (/etc/systemd/system/hysteria-server.service; enabled; vendor preset: enabled) Active: active (running) since Sun 2023-09-17 10:04:16 UTC; 1 day 22h ago Main PID: 518765 (hysteria) Tasks: 5 (limit: 1110) Memory: 14.6M CPU: 2.154s CGroup: /system.slice/hysteria-server.service └─518765 /usr/local/bin/hysteria server --config /etc/hysteria/config.yaml

Thanks for your answer. I've checked the article listing possible problems, but it didn't solved.

1. The server is not running Server is running, confirmed with systemctl.
2. The port is blocked by a firewall

      ubuntu@instance:~$ sudo lsof -i:443
      COMMAND     PID     USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
      hysteria 555625 hysteria    3u  IPv6 8928487      0t0  UDP *:https

3. The server is running at a different address or port. After confirming that the domain and port are correct.
4. The server is listening on a network that's inaccessible to the client. The server can be reached, but the packet loss rate is relatively high.
5. The domain name is not resolving to the correct IP address. Domain resolves correctly.
6. Incorrect obfuscation settings The config file is given above.

I've never used Oracle but don't they have firewall settings on the console? Have you opened the port there

I also have the same problem

Test if your UDP port is reachable with nc first. https://help.ubidots.com/en/articles/937233-sending-tcp-udp-packets-using-netcat#udp-client

This error is due to the default security list of the VPS not having udp rules open. Thank you for your patience.
