I have a large number of file download links in a txt
file. I am trying to write a python
script to download all the files at once, but I end up with the following error:
SSLError: [Errno 1] _ssl.c:499: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
The file is being downloaded via intranet.
I tried to download the file via browser and I got a pop up with some certificate
. I tried to google it but didn't find a way to solve this.
Got this issue today and after wandering for several hours just came to know that my server datetime was wrong.
So first please check your server datetime before going so deep in this issue.
also try doing
>> sudo update-ca-certificates
Experienced this myself when using requests
:
This is extremely insecure; use only as a last resort! (See rdlowrey's comment.)
requests.get('https://github.com', verify=True)
Making that verify=False
did the trick for me.
Got this same error recently in a python app using requests on ubuntu 14.04LTS, that I thought had been running fine (maybe it was and some update occurred). Doing the steps below fixed it for me:
pip install --upgrade setuptools
pip install -U requests[security]

I've experienced the same issue because of certifi
library. Installing a different version helped me as well.
Normally updating certifi and/or the certifi cacert.pem
file would work. I also had to update my version of python. Vs. 2.7.5 wasn't working because of how it handles SNI requests.
Once you have an up to date pem file you can make your http request using:
requests.get(url, verify='/path/to/cacert.pem')
could also happen when your local time is off (e.g. before certificate validation time), this was the case in my error...
The server certificate is invalid, either because it is signed by an invalid CA (internal CA, self signed,...), doesn't match the server's name or because it is expired.
Either way, you need to find how to tell to the Python library that you are using that it must not stop at an invalid certificate if you really want to download files from this server.
