A new revision of Microsoft Edge changed the way some of the GAIA portal web pages would browse. Since they are self-signed certificates, you usually got the message that the site was unsafe. You would click Advanced, then use the link that you wanted to proceed to the site anyway.
Well, there is an alternate message the says "you can't visit 192.168.100.1 right now because the website sent scrambled credentials..." No method to go on to the page. There is a workaround.
Click on the tab of the page and type thisisunsafe You do not need to press enter or refresh, the site will automatically reload.
PhoneBoy had mentioned this in another thread, but you might have had issues finding it looking for the message.
