execute ./supervisor , run localhost:8888 error
The following error occurs：

How to solve this problem？
thanks！

Try this:

Adjust the parameters of TCP write buffer：
vim /etc/sysctl.conf

Add this line in the end of this file:
net.ipv4.tcp_wmem = 32768 65536 16777216

Then save and exit, execute
sysctl -p

Restart hue.

I meet the same issue. And this won't work for me. I'm using ubuntu 16.04 and hue master.

Same problem here.

Hue: 4.11.0
Python: 3.8.16

Any update?

May be you can change setting gunicorn_work_class to gthread to solve this question:

[desktop]
  #...
  gunicorn_work_class=gthread
