Running a site without HTTPS in 2026 is pretty wild. Most browsers will complain. A lot of links break because the browsers assume HTTPS and you have to hand-edit the location to remove the S.
Most browsers will eventually take you to an HTTP page after warning you, but I wouldn't be surprised if some won't. So here's what I would do:
Step 1 try a different browser. Most devices have more than one browser available.
Step 2 talk to Claude. This is something LLMs are good at. Tell is "I'm using X device and Y browser and I want to get to a web site with only HTTP" and it will know how to get into the browser's settings and turn off the security or what alternate browser to use or what other solution is appropriate.
Note that it's free to get a HTTPS certificate today. We are going to lose more an more people to this problem. At some point next year some of us are going to have to break out the 486 from the garage, fire up Windows 98 and keep a separate computer around just to access TMP.
I'm sure adding HTTPS to TMP would be quite the chore, but an LLM would make it much easier.
