I have a script in python that makes request to GOV APIs in Poland. When I run it locally - it works well, I have response in 2 seconds.

If I run it on the server (Amazon EC2) then something brokes. I'm waiting a lot of time or getting timeout.

Does someone know is this my fault or maybe GOV API fault?

AD 1. I have also Airtable API on the same server and it works well.

AD 2. I noticed that GOV APIs doesn't support IPv6 connection. Only IPv4.

Please give me some adivces.
