This guide is an overview of frequently encountered problems when connecting to nx.reading.ac.uk. It’s a continuing work in progress, so the list is not complete. Below are some common solutions. If you encounter a problem that isn’t solvable by the suggestions below, please raise a ticket to the DTS Self Service Portal<\/a>.<\/p>\n

    \n
  1. Login fails with error ‘Authentication failed, please try again’.<\/strong> This error most commonly happens, when you’ve mistyped (or used the wrong) password. It can also happen when you’ve entered your username as ‘xx123456@reading.ac.uk’ rather than just ‘xx123456’. Please note that adding ‘@reading.ac.uk is not required when connecting to nx.reading.ac.uk.<\/li>\n
  2. \u00a0Login fails with error ‘The session negotiation failed. Error is: Disk quota exceeded’.<\/strong> This happens when your home directory is full. The connection to nx.reading.ac.uk needs a bit of free space in the home directory to be established. To clear some home directory space, you can log in to arc-ssh via command line and remove some data there, as arc-ssh will still let you in despite your home directory being full. If you’ve never logged in to arc-ssh before, have a look at the user guide<\/a>.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
