chats, but still working in private chat
I didnt change any line of code
Maybe someone have an idea what is going on?
What does getWebhookinfo show ?
Debug your code using an update from a group
Well, that's the reason. Your server is sending a 502 response
but why can it response with 502 only in group chats? and why it appeared only few days later?
Couldn't tell. Try removing those pending updates by removing webhook, requesting getUpdates and setting it up again. Btw there is probably something wrong in your code on in your webserver configuration
