Description

I have made a server using the server.handleClient(); and that stuff, but now I 've implemented the universal telegram bot library, which keeps crashing or freezing the esp. At first, the webserver works finely, but when you execute a function from the library and you send a message through the bot, the webserver stops working, and after having the bot answering commands for a short random time, it crashes. It sometimes gives me different stacks.

I personaly think the problem may have to be with teh client breaking the server, and the esp without knowing what to do when receive a request, and that is what makes it to break

BearSSL is merged in #4273 , with alternate BearSSL::WiFi* classes. Although axtls-based classes are still available and even the default, they are planned for deprecation and then retirement, hence won't be fixed. Any issues with BearSSL-based classes should be reported in new issues.
Closing.
