Timeout while await api.metatrader_account_api.get_account(account_id)

[chaskas]

Since yesterday, my Heroku Python app has been timing out on this line:

await api.metatrader_account_api.get_account(account_id)

However, making the same request with curl succeeds.

Because this is the first call before establishing the connection, its failure prevents the rest of the program from running.

Also, the exact same program on my local machine is working fine...

What could I be doing wrong?

This is the error I'm getting:
