Home assistant green stopped working

For 1 month home assistant green worked perfectly, but now I can’t access it.
When trying to enter it says:
Page 192.168.0.8 has rejected the connection
ERR_CONNECTION_REFUSED

What can I do?
Regards

Antonio

Try clearing your web browser cache. Ctrl + F5. Then you may need to log in again.

If that does not work, connect a display up to your Green to see what is going on.

Thanks Tom.
The first option didn’t work.
The second gives the following message:

What I do?

Thank you

Search the from for that error.
