HA Frontend can not be accessed

Configuration Frontend
1

Hello.

I am using HA ver 0.93.1.

And I have done SSL certificate and I can access HA frontend(https://“myddns”.com) at local and outside(external).

Last Sunday, I tried to install websocket_client and requests to apply some custom script.

At first, I might take wrong command at pi account.
pip3 install websocket_client
pip3 install requests (error happend)
after rebooting (sudo reboot)
sudo pip install requests

After installation, I can not access HA frontend anymore.
When I enter HA https page via iPhone safari, the below error message is happened.

‘FetchEvent.respondWith received an error: no-response: no-response :: [{“url”:“https://“myddns”.com/lovelace/default_view”,“error”:{}}]’

How can I solve this?
I am afraid of initializing hassbian re-installation. :frowning:

It is complaining heavily about your tuya switch configuration. Try removing that temporarily from your configuration as a troubleshooting step.

I reply home-assistant.log after I remove tuya switch configuration.

Can you get to the frontend now, after restarting HA?
If not, I would try removing airkorea.
Although the lagacy api password will cause issues in the future, support is currently enabled.

All custom components is removed about warning in home-assistant.log file and the below warning message is only remaining.

But HA https page is still not working…

I found something…

In local, I can access HA frontend. (i.e. http://hassbian.local:8123)

Then… what is problem?
