   2. elasticluster ssh slurm -- I have to export OS_CACERT first otherwise

   3. Error: SSL exception connecting to fqdn:5000/v3/auth/tokens: 
   HTTPSConnectionPool(host='fqdn', port=5000): Max retries exceeded with url: 
   /v3/auth/tokens (Caused by SSLError(SSLError("bad handshake: Error([('SSL 
   routines', 'tls_process_server_certificate', 'certificate verify 
   failed')],)",),))"
