Sheila and I had similar problems, we weren't able to get the realtime graph to come up while connnected to h1nds1 server. Not sure if this is a temporary problem...
The DAQ uptime on the CDS overview screen for h1nds1 is not going up, h1nds0 still works.
I could not find any obvious error messages in any of h1nds1's logs. I restarted the daqd process 09:24 PDT and this seems to have fixed the issue. Investigation continues.
