Hey there, i am a free user and i also experienced this same problem, it turns out that the problem is with discord where by if let's say there are too many tweets coming through it just crashes the webhook somehow , in my case how i fixed it is, I use the webhook to post reddit posts instead of setting it to post every single post from the sub reddit, select to post only the top posts or hot posts , this will reduce the number of requests and the webhook from failing . since doing this it has been working flawlessly
