Debian Lighttpd does infinite redirect loop and fails to connect

Just imagine your running a blog that requires zero maintenance and one day you access it and it doesn’t load!

You try Firefox and then Chrome and finally Edge (the new IE)

You notice that Firefox and Chrome seem to loop and then finally fail - You notice that Edge works….

You notice that cURL works.

Things are but aren’t working.

Finally you notice Firefox is trying to do TLS1.3! Interesting how do I disable that on Debian 9 with Lighttpd? You Can’t!

What’s the fix?

in lighttpd.conf in your SSL section input:

ssl.disable-client-renegotiation = “disable”

ssl.disable-client-renegotiation exists because of a bug back in 2009 - This bug has long been patch in newer versions of OpenSSL and is safe to turn back on.

Disabling this setting allowed you to find the answer to your troubles :-)
