The long-term solution for these issues is to update your `from=` clauses to include patterns based on IPv6 addresses (or hostnames matching the IPv6 addresses). The long-term solution for these issues is to update your `from=` clauses to include patterns based on IPv6 addresses (or hostnames matching the IPv6 addresses).
A short-term solution can be to revert to IPv4 connectivity. This can be done by connecting to a new DNS name which will keep resolving to IPv4 addresses only: `jureca-ipv4.fz-juelich.de`. Another option is to disallow IPv6 in your SSH client. For OpenSSH, this can be done with the command line option `-4` or the configuration setting `AddressFamily inet`. In PuTTY the protocol can be overridden with the setting '_Internet protocol version_' in the '_Connection_' pane. **A short-term solution**: Revert to IPv4 connectivity.
1. Disallow IPv6 in your SSH client
- PuTTY: Set '_Internet protocol version_' in the '_Connection_' pane. See figure below.
- OpenSSH: Command line option `-4` or the configuration setting `AddressFamily inet` in `.ssh/config`
2. Connect to a new DNS name which will keep resolving to IPv4 addresses only: `jureca-ipv4.fz-juelich.de`.
