<drumroll...>Tada!....

It suddenly is working. I didn't change a thing.

@[email protected] suggested I get suspicious about my country or ISP. Should I worry, now?!... :-(

Seriously, did the f-droid folks change anything on their end?

I tried to use some webproxy to test other locations and had the same result - only difference is the name offered for the file to download.

Thanks.

It happen in both http and https, but http wold redirect to https wouldn't it?

The cert is letsencrypt, yes. Didn't verify the details, though.

Ahha! With a blank bowser profile directory it works as expected. It has to be HSTS, right? Now, how do I fix this?

Just a thought: could it be hsts?

Bang! Firefox on windows - same thing!

Both hosts and resolv.conf are ok.

Well... just saved one of those files, renamed it to file.html and opened it with the browser. Seems to be the f-droid homepage lacking the css.

What could it be? That doesn't happen on any other website.

Does your ISP or government interfere with your Internet access? When you view the cert, does it show that it was issued by Let’s Encrypt?

I hope not.

I can't inspect any cert. The browser url bar doesn't show the padlock.

On my desktop, the name is something like <random>.ptrom. Im from Portugal. Could ptrom have anything to do with it?

Actualy, downloadfile.bin.

Forgoy to say: firefox, chromium, epiphany on debian with gnome
