We are having problems with our test bot that has been developed.
It works absolutely fine in the emulator talking to the remote bot hosted in Azure using ngrok but I think that effectively bypasses some of the authentication.
In the Portal framework we have enabled 3 channels web chat, Skype and facebook messenger.
Firstly when we login to the Bot Framework portal and try to test we get a cannot send message. The bot also does not reply from any of the configured channels. Strangely all these channels were working just over 2 weeksa go and the test client in the framework portal was also working. As far as we know nothing has changed to stop it working.
