Connection problem with internet requiring log in

Things I have tried

What I’m trying to do

I need to log in in order to use the sync function. However, my desktop in office requires ID and password to access the internet. While I am trying to log in my account in Obsidian software in my desktop, the page keeps loading and cannot get into the log in page. I suspect it is due to the network requirement of my desktop which needs to input the ID and password.

Anything I can do to make it connected to the internet.

In web browser setting, there will be a pop up window to prompt me to enter the id and passwrd for internet access.
