Today, on https://www.youtube.com I got:
"An error occurred during a connection to www.youtube.com. Peer reports it experienced an internal error. Error code: SSL_ERROR_INTERNAL_ERROR_ALERT" (Browser Firefox)
With another browser (Chromium) same problem - no connect.
The exit node was 163.172.212.115 (https://check.torproject.org).
After a while, with another exit node, no problem anymore.
Temporary fault or bad exit node?
