Common Issues

I keep getting HTTP 401 Unauthorized messages*

This means that the given username/password combination is incorrect. Note that if you created your account recently it could take a while (a few days?) until you can use that account on apihub and therefore sentinelsat too. You can go here to test access on the apihub endpoint.

The query fails with HTTP 500 connection timed out

SciHub servers are known to have outages due to high demand, try again later.

Query fails with ‘Longitude/Latitude is out of bounds, check your JSON format or data.’

Standard GeoJSON specification contains only WGS84 format, check if your data complies with it.

My search returns 0 results

Maybe there are no images for the specified time period, by default sentinelsat will query the last 24 hours only.

A query to Eumetsat CODA fails with HTTP 401 - Full authentication is required even with the correct password.

CODA does not allow the following special characters in passwords:
~ ! @ # $ % ^ & * _ - + = ` | \ ( ) { } [ ] : ; " ' < > , . ? /
See also issue #315.

I get the warning ‘The query string is too long and will likely cause a bad DHuS response’.

The query sent to the DHuS server is too complex and will likely fail. You can counter this by decreasing the query length by removing parameters or simplifying your polygon, i.e. remove vertices or decrease coordinate precision after the decimal point.

Anything else?
