Hi everybody!
Today my code has decided to do not collaborate anymore :(...in fact this error message has started appearing a couple of hours ago in the command window when i try to connect to a specific website to scrab some weather data.
Could not establish a secure connection to "nomads.ncep.noaa.gov". The reason is "error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed". Check your certificate file (C:\Program Files\MATLAB\R2018b\sys\certificates\ca\rootcerts.pem) for expired, missing or invalid certificates.
I have checked if other discussions about the same trouble were available but nothign seems to be similar to mine.

hi, could you show me the lines you used to solve the issue?
I'm using this:
options=weboptions;
options.CertificateFilename=('');
websave(URL,options);
But is not working. it says: Unrecognized function or variable 'URL'.
