SSLError while pushing to Datastore

Hi!

I am using CKAN 2.9.2 and I am currently having a problem with an Excel file in a dataset that I try to manually push to the Datastore.

```
Traceback (most recent call last):
File "/usr/lib/ckan/datapusher/src/datapusher/datapusher/jobs.py", line 363, in push_to_datastore
response = requests.get(

raise SSLError(e, request=request)
requests.exceptions.SSLError: HTTPSConnectionPool(host='ckan.example.com', port=443): Max retries exceeded with url: /dataset/12baf1af-1b92-4b37-834c-660ee75e19e5/resource/9e577061-19a0-47e4-ba5b-e0a4b3da4063/download/file.xlsx (Caused by SSLError(SSLEOFError(8, 'EOF occurred in violation of protocol (_ssl.c:1131)')))
```

I put the `SSL_VERIFY` to False in the config file but it did not help.

What can I do?
