So currently when I try to load a localhost page without any Active Directory Authentication, my page loads in like 3 seconds. However when I log in and try to load the same page, it takes around 90-100 seconds. But this is only happening to my specific login. It loads at good speeds when logged into any other Active Directory account.
Initially we thought the issue was my laptop, so I started using a laptop that was located in our corporate office. I am a remote worker, so I connect to the VPN and then remote to that laptop. And specifically when using that laptop which is not connected to my home network, my AD Account works just fine and loads quickly.
After doing all the diagnostics we could, we just ended up sending me a new laptop but turns out the issue is persisting onto this new laptop.
In summary, my authenticated page only loads quickly when not connected to my home network. But my secondary account works just fine when connected to my home network. In both instances I am VPN'ing to the corporate network from my home network.
Let me know if there is any additional information I can provide. Thanks!
Edit: Also I have not made any changes to my network/router/modem in well over a year, and the issues only started popping up about a month ago.
