Errors: SSL Certificate or Json decoding failed

[Opadera]

Hello,

I am trying to implement your tool on a new computer.
running on scihub.coperinicus/s2/ i get SSL certificate problem: self signed certificate in certificate chain

trying with scihub.coperinicus/dhus/: API response not valid. JSON decoding failed.

I tried logged in and with the guest//guest account. The JSON is fine and works on another computer with an older version of the sentinelsat.

Any ideas how I can get the new version to run?

This error likely depends on your installation of pyCurl and the CA bundle it uses. Most of the time this issue can be solved by installing certifi - as noted in the troubleshooting section of the docs.

I already checked certifi, it's installed and updated.

Did you try passing through a cacert.pem yourself? We had this issue before (#1) and it is not related to sentinelsat but rather homura>pyCurl>CA certificates. The solutions mostly circle around using a different version of pyCurl, providing the cacert.pem yourself and/or installing openssl dependencies. All very dependent on your OS, your Python installation, environment, etc.

On Windows I saw best results by using conda.

I also just verified that this is not a sentinelsat issue. The download is working fine on Ubuntu 14.04 and Win7 x64 with Python 2.7 and 3.4.

I uninstalled conda and installed pycurl=7.19.0, updated certifi and it works now.

thanks again for your input
