NOAA Grib Data Download

We have used Saildocs happily for some time.  But we want NAM from NOAA.  When we try to download, we receive error message "Unknown Server Error".  What is fix?

It seems to be working here. You could try the previous run

Was there meant to be more to your reply ending "try the previous run"? 
We also use Predict Wind.
We used Expedition on another laptop for six years, and occasional tries of NOAA never succeeded.

You can select earlier runs - the second control down at the top left.

​Do you have the current version of Exp? The NAM changed a couple of months ago, so we have to point it to different data.

The NOAA server we use for this data can be very slow though. The Great Circle service can also provide the NAM data, although they re-project it to a lat/lon grid.

The 1 June update solved the problem - thank you!

NOAA grib download  error - Requested URL Not Found
v10.10.18  Windows 10 
GreatCircle and Saildocs download works

Changed multiple settings on the download parameters - WiFi, LTE connection not an issue
Did NOAA change their URL? How can this be updated?

Yes, NOAA changed. Fixed for the next update.
