302 - ANS2610S TCP/IP-Übertragungsfehler zwischen dem Client und der Servermaschiene.

This error message indicates a connection problem between the client and server.

Check connection

You can check the connection between your computer and the server yourself.

Linux or macOS:

Use the command nc -vz <IP or FQDN> <port>:

nc -vz s27.abs.lrz.de 1770

Windows:

Under Windows in Powershell, you can use the command test-netconnection <IP or FQDN> -port <Port>:

test-netconnection s27.abs.lrz.de -port 1770

Try IPv4 and IPv6

Another possible error is incorrect connection information in dsm.sys and dsm.opt.
Set the option shown below in dsm.opt or in dsm.sys.

COMMMETHOD       TCPIP

This means that IPv4 is used to establish the connection.
If this does not lead to a successful connection, you can also test IPv6 by changing the COMMETHOD accordingly:

COMMMETHOD       V6Tcpip

Check firewall

Last but not least, the server address may first have to be activated in a local firewall. Ask your network administrator whether a firewall for the network could be the reason and whether he can allow the IP of the ISP server.
