Apparent Stall

I don't know if this is a Newsbin problem or a News server problem.
For the last few days when I start Newsbin, it appears to start downloading headers and stops.
No error messages.
Just three lines in the log:
High PAR Pausing Enabled
High Par2Repair -Single-core 4.0
High MessageId Filter: enabled
[there is nothing in the filter]
Until this started, immediately after staring Newsbin, I'd get a ton of news server errors. Sometimes it would continue to download items and sometimes not. If I restarted Newsbin, it would sometimes restart downloading, but still showing news server errors. If I left Newsbin open overnight, it would appear to download a few segments of a file every few hours and usually complete the file download
But not now.
Now there are no news server errors, but only a rare downloading of anything including headers.
