titleI cannot establish an ssh connection to the login nodes running Rocky Linux 9. Do I need to generate a new ssh key?

No, your ssh key remains valid. We have seen this kind of problem for Windows users with an outdated version of PuTTY. Updating to a more recent PuTTY (≥ 0.81) solved this problem. The same holds for WinSCP which needs to be up-to-date, too.

titleMy jobs generate no output, they seem to hang. A few days ago they were working fine. What happened?

This behaviour is observed for jobs submitted to the old CentOS 7 partitions (see the table above). Please make sure you submit such jobs on blogin1 or on blogin2 which currently still run CentOS, too. The generic node name “blogin” resolves to login nodes already running Rocky Linux 9 - they should not be used for job submissions to the old CentOS 7 partitions.
