I know this is not a new subject and previously reported in 2020. but this issue seems be happening again in 2023. Can you anyone let me know if this issue is happening to some of you and what is the fix to this? thanks!
Please let us know what specific problem you are having. Occasionally there are intermittent server issues that might cause problems, but the downloads should be working.
Weather file downloads from the NSRDB should be working in SAM (from the Location and Resource page). Are you seeing this error from SAM or from the NSRDB website?
Please be sure you are using the latest version of SAM. Older versions of SAM may not work with the latest weather file downloads from the National Solar Radiation Database (NSRDB). You can download the latest version of SAM from sam.nrel.gov/download.
