MATLAB certificate problem with webread
When I try to use Mdbnomics I receive the following error message:
'Could not establish a secure connection to "api.db.nomics.world". The reason is "error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed". Check your certificate file (C:\Program Files\MATLAB\R2019a\sys\certificates\ca\rootcerts.pem) for expired, missing or invalid certificates.'
To circumvent the problem I added to the file ‘fetch_series_page.m’ which is in ‘mdbnomics-master\src\utils’ below row 39 [options = weboptions('ContentType','json');] the following instruction:
options.CertificateFilename=('');
This occurred both on Windows 10 and MacOS machines respectively with MATLAB2019a and MATLAB2017b.
