The program should allow to run several https get requests with one aiohttp.ClientSession as the documentation suggests. It is intended to run a telegram bot.
I was not able to catch the exception with try ... except. Therefore the program hangs when exiting. During extended sessions the error is printed in the command windows (but not in the error log).

As the error information is very unspecific I could not really isolate the source and have a short code to reproduce the error. A sample code is on github under https://github.com/fhag/telegram2.git In order to run the code you will need an API token from telegram of your own bot. This error showed up the first time when I upgraded to python 3.7.1. Python is running on Windows 10.
