Why can't I log into the network?

The authority I work for now sends all employees to the home office. Because we don't have enough laptops, a lot of people have to work with a token on their own private computers. That worked pretty well for me so far, but now it no longer works. I can no longer call up the homepage, it no longer works on any browser.

I suspect that I changed the settings by mistake. Can someone send me a little guide on how to undo this?

Wow, yes.

Because we don't have enough laptops

Wow. That came as a surprise now. I call that preparation.

How are we, who know even less about what you have done, to explain to you how to undo what you do not know? Your error description is even less meaningful than "The Internet doesn't work".

It's best to call your IT department tomorrow morning and solve the problem with them. This can't be done via remote diagnosis.

Sure, I'm your authority and you are my user and I'm your IT supporter. What is your helpticket ID?
