Exactly. Decoding the unexpected server message myself gives me . That's also probably why I'm having problem with USGN verification, but I don't know, I'm just guessing. I'd love to solve this problems together so if you have time just let me know.

It's not new, It happens even before the DNS change.

@ MikuAuahDark: This sounds like you're not getting the full UDP message for some reason. Weird.

I enabled a HTTPS redirect rule and excluded CS2D as a user agent. So now you should always be redirected to HTTPS on unrealsoftware.de but avatar downloads in CS2D should still work (and use HTTP instead of HTTPS).

Some users are using non HTTPS images here so you will probably see some "insecure" warnings because of that in your browser. I'll try to get rid of that stuff in a next step (simply by enforcing HTTPS on all external content).

Yeah. I tried to perform packet capture and the packet seems fine, I receive so maybe it's CS2D side? Anyway if you want to debug this thing out just let me know in UnrealSoftware Discord (same username as this) because communicating with the forums may not be ideal.

Also thanks for the HSTS.

This isn't real HSTS but you're welcome

Okay thank you very much for your offer! Will try to contact you on discord as soon as I find the time to debug this thing!

The Icon Theme in here doesn't work and throws an error message, Same for Valid XHTML 1.0 Transitional.

Well.. okay. Apparently that website doesn't exist anymore. Will just link to wikipedia then.

That page has exploded.

EDIT: Same for CS2D FAQ and Carnage Contest FAQ.

Man, it's "links.php" not only "/links", same for the other pages.

@ BcY: There was a feature before that could make the website work even without the file type tag. Some links stopped working because of that. There for example.

it's called htaccess, and it's all up to DC.
