I would like to ask for a help on how to fix the SSL error I'm having on a fresh installed QGIS 2.14.1 version. It seems to me it's the reason why vector, raster, and some other tools won't work when I use it. It crashes my QGIS every time. Can somebody point out how can I possibly fix the problem?

Please see attached images for reference.

  • It appears from the error that you are using a self signed certificate. What happens if you tick the box Save SSL server exception

  • I have similar problem. "SSL error occured during access of URL" but our URL referred to is qgis.org/version.txt Is it possible to not get the error message in the first place? Regards: Fredric

I don't have enough reputation to comment so I copy / paste my answer here since this question has more views.

I had a similar issue during QGis 2.18.10 startup.

SSL Certificate Errors occured accessing URL :

https://ubuntu.qgis.org/version.txt

Unable To Get Local Issuer Certificate: The issuer certificate of a locally looked up certificate could not be found

I fixed it by going to https://ubuntu.qgis.org/version.txt with IE.

Alternatively, using Powershell :

Invoke-WebRequest https://ubuntu.qgis.org/version.txt

or (for Powershell < 3.0)

(New-Object System.Net.WebClient).DownloadString("https://ubuntu.qgis.org/version.txt")

My guess is that any of these actions add the qgis certificate (or maybe let's encrypt CA) to the certificate store.

Add the system Environment path to give the permission for SSL Request in QGIS -

System Environment setup -:

Variable Name- : GDAL_HTTP_UNSAFESSL Variable Value- : YES

Variable Name- : GDAL_HTTP_USERAGENT Variable Value- : Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36
