I am trying to host two bots on one local machine. For simplicity, let’s call one “Bot A” and other “Bot B”.
I made route for one as “mydomain.io/a”, for other as “mydomain.io/b”:

bot = TeleBot(TOKEN)
app = Flask(__name__)
bot.remove_webhook()
bot.set_webhook('mydomain.io/a')

@app.route('/a', methods=['POST'])
def tovc_webhook():
    if request.headers.get('content-type') == 'application/json':
        json_string = request.get_data().decode('utf-8')
        update = types.Update.de_json(json_string)
        bot.process_new_updates([update])
        return ''
    else:
        abort(403)

...sum working code...

if __name__ == '__main__':
    app.run()

And same code for another one, but bot.set_webhook(‘mydomain.io/b’), @app.route(‘/b’, methods=[‘POST’]) etc.

Any of the bots work by itself, but when i try to start both at the same time, – one, that was started first continues to work, but later one does not do anything.
(triple-checked that routes and webhooks and etc are not same, basically triple-checked everything)

Later I’ve come up with an idea. I’ve created one more file, “C.py”:

from a import bot as abot
from b import bot as bbot 
app = Flask(__name__)

abot.remove_webhook()
abot.set_webhook('mydomain.io/a')

bbot.remove_webhook()
bbot.set_webhook(mydomain.io/b)

@app.route('/a', methods=['POST'])
def tovc_webhook():
    if request.headers.get('content-type') == 'application/json':
        json_string = request.get_data().decode('utf-8')
        update = types.Update.de_json(json_string)
        abot.process_new_updates([update])
        return ''
    else:
        abort(403)

@app.route('/b', methods=['POST'])
def tovc_webhook():
    if request.headers.get('content-type') == 'application/json':
        json_string = request.get_data().decode('utf-8')
        update = types.Update.de_json(json_string)
        bbot.process_new_updates([update])
        return ''
    else:
        abort(403)
if __name__ == '__main__':
    app.run()

i.e. transferred and merged some of code of both bots into C.py.
Surprisingly, that did work, but I got two more problems with that.
Problem 1 – I can’t start bots separately now.
Problem 2 – for some reason, exceptions and error don’t show up anymore, as like I did try: <code> except: pass.

What am i doing wrong?
Also, please, don’t ask why I need two bots at the same time on ngrok. Trust me.
(oh and also I don’t want to make bots on different ports for one reason)
