SSL connection errors from Apache
- by Yang
I'm running a (self-signed) SSL cert site on Apache/2.2.14 on Ubuntu
10.04, but various browsers are giving errors on half the connection
attempts. Just now saw this transient error from Chrome:
"Error 126 (net::ERR_SSL_BAD_RECORD_MAC_ALERT): Unknown error."
Hit refresh and the problem goes away for a while.
wget too:
$ wget --no-check-certificate https://dev.foo.com/deps/
--2010-09-08 19:30:26-- https://dev.foo.com/deps/
Resolving dev.foo.com... 184.72.53.220

Run it right away again and it works:

I don't administer the network, hardware, etc. - this is all running on Amazon EC2. I'm not running a load-balancer or anything else in front of the server. I'm making direct TCP connections to that host (AFAIK).
Any ideas? Thanks in advance for any help.
