SRT/VPN HELP REQUEST

I'm in the Personalization SRT project and I spent an ungodly amount of hours last week trying to troubleshoot why I cannot task inside of the platform. I even had my credentials changed because I had an old ad worker account from long time ago and we thought it could be something to do with that but with my new credentials I'm getting the same errors.

I know it's something I'm doing wrong and I think it has to do with the VPN and the way I'm opening the windows and when I'm turning it on, and what windows or tabs I have opened.

Is everyone just opening it in a new tab or how are you logging into the wfe profile? How are you logging into the VPN? Because it only lets me enter the portal it doesn't ask me for the WFE like it does in the project instructions. I filled out the project form and the lady has been very helpful and really cool but I'm still having this issue and I need to get back to tasking. Any help would be very appreciated.
