If I try to save the URL https://www.uni-ms.de/de/
using the Wayback Machine (archive.org), I get the following response:
However, the site is perfectly fine, and I haven’t been able to find anything strange in the HTTPS certificates or HTTP response headers, either: https://www.uni-ms.de/de/. Saving the HTTP version http://www.uni-ms.de/de/ works without issues, too. What’s the problem here?

There's something about the way this server uses SNI that is incompatible with Java's libraries:

So no, our crawler can't talk to it over https. I haven't seen this particular problem before.
This one works: http://web.archive.org/web/*/https://www.uni-muenster.de/de/ you can see the save I just made.
Surfing the tubes of the Internet, this appears to be a change that the server could make to not confuse Java:

[Earlier I claimed I had saved it, I wasn't paying attention and I was actually looking at an earlier snapshot.]
