Socket connection is closed every minute

Question

I'm configuring a Flask-SocketIO server.

When locally connecting a socket (http://127.0.0.1:5000), it's normally working. But after deploying it into my GCP virtual machine, sockets connected over https are closed and reconnected every minute as shown below (looks like socket connection requests are timed out at this interval).

I've already tried with all async modes, including eventlet, gevent, and threading as well as gunicorn and uwsgi. Some configurations allow a 2-min timeout but no approach resolves the issue fundamentally.

How can I solve this?
