Does anyone else experience a “Loading …” message forever with the Fortran Discourse page then failing to load on Windows 10 OS Enterprise version running Microsoft Edge browser and Zcalar and Microsoft Security for internet security in a corporate enterprise environment?

We have a new experimental scientist in our customer team, she is interested in trying out a computational career for some time in order to care for and be next to her ailing parents in another country and thus be able to work remotely. She is learning C#, C++, and Python. She has used MATLAB and some Visual Basic for Applications in Microsoft Excel. After a separate work meeting with me, she got interested in Fortran and took a look at fortran-lang.org which was fine. However she has not been able to load the Fortran Discourse page on her workstation. She tells me she then tried several of her lab colleagues’ computers and none of them were able to load the Discourse page.
The above is a screenshot she notices in the Edge browser.
Is there something that prevents the Discourse page from working in corporate Microsoft-centric environments?
Can this be related somehow to the Fortran Discourse not showing up on Microsoft Bing?
