Why files stopped downloading via telegram bot api?

Question

Telegram

Good afternoon.
I have a telegram bot that posts audio to a private channel every day at a certain time. Yesterday everything worked, but today when I tried to download the audio I got the answer "413 Request Entity Too Large". To interact with the bot api, I use the go-telegram-bot-api library . Judging by the source codes, loading occurs using InputFile, i.e. the contents of the file are sent in a POST request to sendAudio . According to the documentation, I can upload audio files up to 50Mb, and photos up to 10Mb, but now I can't even upload the audio files that the bot successfully uploaded yesterday.
It was also found that a 11Mb file (11608181) is being loaded, but a 413 error is returned for a 14Mb file (14595622). The files are loaded successfully through the desktop application.
I understand the problem is fresh and I have not found a solution yet. Perhaps someone also encountered it and found a way out. I suspect that the problem is on the telegram side.
I will be grateful for any advice. Thank you.

In general, the situation resolved itself. Now everything works correctly. Apparently the problem really was on the telegram side, it was found and fixed. The question is closed
