I know that there are many topics about connectivity issue from Iran. But I think there is a solution.
When I request from iran with curl -v, it freeze when after:
Connection state changed (MAX_CONCURRENT_STREAMS updated)
But when I request by other clients like httpie, python requests, wget and … there are no errors. As far as I know this clients don’t support http2. Do you think Iran connectivity issue can be fixed by making users able to disable http2?
