Hi!
I have some bots from which I'm transferring items to my main.
However, yesterday, I've faced with InternalServerError <- POST https://steamcommunity.com/tradeoffer/new/send
|SendTradeOffer() Не удалось из-за ошибки: There was an error sending your trade offer. Please try again later. (15)
issue.

All bots worked correctly for months. I don't know how to fix it.
I've tried to use VPN, tried to start ASF with all of my configs on clean PC - nothing worked.

From 7 or 8 attempts, I've got only 1 trade offer, other are still failing.

I use !loot^ asf 730 2 command.

Upd: Solved

FYI: I didn't have any problems for months, but I've suggested that the issue is connected with friends in steam. So, I've added to bots SteamTradeToken and it worked!
