> Did you resolve this issue? nope, I just change my field name.

here is same issue ``` queryset = MyModel.objects.filter(start_date__year=mydate.year, start_date__month=mydate.month) str(queryset.query) Traceback (most recent call last): File "", line 1, in File "...\lib\site-packages\django\db\models\sql\query.py", line 263, in __str__ sql, params = self.sql_with_params()...

I've been troubleshooting for a while with the same problem. In my case, it was solved by adding ipv6 to the loopback interface by setting ``` net.ipv6.conf.all.disable_ipv6 = 0 ```...
