Error in online access to vue project

is actually a very strange event. What happens when the boss visits the test background:
this background project has been running normally for a long time. The boss has no problem when he visits and uses it in the morning, but it appears

when he visits again in the afternoon.

is not visiting our project. I don"t know where this page came from.
I was stunned, and what"s even more amazing is that this happens only if the chrome browser on the boss"s macbook computer visits it. I can"t find the reason. I personally suspect that the boss"s computer has been hacked.
have any brothers and sisters seen this before? Is there a solution?
