2 years ago I tried another ESP32 (WROOM-32) just to see if the problem is the hardware or the software. And - surprise - same issue, so the problem seems to sit in front of the laptop. :)
I switched on the debug messages from the lib and this is what i get (see below)
It looks like the program receives the "hello" and responds, but afterwards something goes wrong. It cannot connect to the server. The behavior in telegram is that I get the response "hallo" from the bot but no new message (also after reset) will be received. The ESP32 board receives the message "hallo" again after each reset. (see picture)

I already tried ArduinoJson v6.18.0 as suggested by other users instead of the latest one, but without success.
Hi,
I am using a LilyGo ESP32 ePaper hardware and I cannot properly receive messages with it.
I flashed the Echo example at the uC but it is not able to receive a message, which was sent to it after the uC finished setup(). In case a message was sent earlier, then it will be received in the first loop() run and a response will be sent back. Any other message later on will not be received again.
When starting my ESP8266 board, which is also connecting to the same telegram bot, it will again receive all (!) messages, which were received and responded by the ESP32 and/or the ones the ESP32 did not receive.
Has anyone had already the same problems with an ESP WROVER E board?
