verification problems???

Fairly new to python and stuff, have used this in the past to download magazines just fine. Bought some new ones and ran into some issues, one of which was already described here due to problems with the "original" quality setting. I downloaded the newest version of the code and tried to get the extrahigh quality to work, but something is still going wrong. I've included the readout below:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

I do not have enough experience with coding to even begin to understand what this means. Thanks in advance for your help :)

Looks like verification of the certificate failed. If there is an option to not verify, that would probably fix it. If not, sounds like a feature request 🙂

I'm afraid I cannot replicate this with the information provided. Still stuck with the original quality problem as I haven't had the time to devote to researching it, but just testing again now with high and extrahigh quality I'm having no issues with my limited number of previously purchased magazines.

To further investigate your problem, can you try passing a plain http URL to the script instead of https? I've just checked and the pocketmags data sources don't redirect to https if you only use http for the initial query.

Looking at the traceback it looks like Python can't find an up-to-date set of SSL certs on your computer given that it says unable to get local issuer certificate. Try running pip install --upgrade certifi from the terminal...

What operating system are you using?

Edit: Also dropping this in here for reference, and in case you are using MacOS: Rapptz/discord.py#423 (comment)

Using http did make it work. I'm using MacOS and have upgraded certificates, tested it again and the issue appears to be resolved! Thank you! :D

Glad it's resolved for you!
