Logging onto wifi sites

Hello…since obtaining a school issued MacBook Pro, I have had the following pop up appear every time I attempt to log onto a new wifi account - hotels, coffee shops, etc. I close it out and then launch Safari, and after a few attempts can get onto the log in page for the wifi account and log in. It works, but it is frustrating as I should be able to log in with the pop up window. My personal MacBook 12 inch does not have this issue. It may be a restriction by the university, but wanted to ask the forum if there was a fix. Thanks

Try to navigate to neverssl.com first, just to see whether there is an issue with a captive portal preventing the correct wifi setup?

Thanks - I will try this.
