Error 504 when call getFile method

[ysset]

I am trying to call getFile method with my test bot but it always return 504 error

https://api.telegram.org/bot<botToken>/test/getFile?file_id=<big file id from 'photo' bot event>

The method works fine, if i try to call it with wrong id i get an error

{
    "ok": false,
    "error_code": 400,
    "description": "Bad Request: invalid file_id"
}

But if photo id is valid i get timeout error(504)

{
    "ok": false,
    "error_code": 504,
    "description": "Gateway Timeout"
}

Test DC isn't expected to be reliable. It seems to have issues with file downloading now.

Is there another way to get a link to a file by another method?

No. The file can't be downloaded in Test DC now.
