I have two computer both with a fresh quasi-identical Slackware install. I use Waterfox 56 for browser and try to access my websites on my local webserver. The local webserver uses TLS certificates from my own CA that are correctly imported into the two browsers.
One of my computer cannot load the local websites correctly and hangs at "Performing a TLS handshake". I try clearing the cache and rebooting, nothing worked.
I just tried with another browser (lynx) and got a similar result.
What could be the cause of my browser hanging at the TLS handshake?
I have news: After rebooting my laptop, it can no longer load the websites, like my other computer. But I may have found something: When I try connecting with openssl, like so:
openssl s_client -connect <server_ip>:443
CONNECTED(00000003) and then nothing...
Also ssh sessions on the server freeze sometimes, so maybe it is a problem with the server after all.
