I cannot contact external servers/services

Problem

I have to contact an external server from within the NHR@Göttingen, but it does not work, what can I do?

Solution

NHR@Göttingen network connectivity is restricted. You can connect to the login nodes from any remote host. Outgoing connectionsare restricted to SSH, HTTP and HTTPS from the login nodes (or the compute nodes when using the -C inet slurm option). Contact NHR@Göttingen Support if you need to connect to ports other than the three mentioned.
