I am having a very weird problem when browsing a HTTPS site we host with Firefox.
I have no problem with most of the pages (we are using PHP/FreeBSD), but a few of them, when accessed with latest versions of Firefox (3.0.x), are randomly (not always) throwing this SSL error:
An error occurred during a connection to myserver.mydomain.com. SSL received a record with an incorrect Message Authentication Code. (Error code: ssl_error_bad_mac_read)
I don't know if it has something to do with the problem but my server has two NICs:
- EXTERNAL_IP_ADDRESS (public IP)
- INTERNAL_IP_ADDRESS (lan IP)
And I am seeing the error when accessing the page through the INTERNAL NIC.
I don't see the error with latest IE, Safari or Chrome.
My SSL certificate was issued by GoDaddy.
The strangest part of all is that whenever the error occurr, I can see the right page for a fraction of a second before Firefox shows me the error on a complete new page.
Thanks a lot.
