WRT54GL + Tomato = SSL ERROR / No https access

After flashing my good old WRT54GL (v1.1) from original Linksys firmware (v4) to Tomato (1.28), I couldn't access the webinterface over https! :shock:
By default, Tomato's webinterface over HTTP is disabled... :?

Firefox (v71.0) refuses to connect, showing the following error message:
Secure Connection Failed

An error occurred during a connection to SSL peer rejected a handshake message for unacceptable content.


The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
Please contact the web site owners to inform them of this problem.

Unfortunately, you don't get infos or details about Tomato's certificate that seems to be "outdated" in a serious way.
Chromium is even more silent and just says: "ERR_SSL_PROTOCOL_ERROR"


I haven't been able to re-generate a new certificate that firefox is happy with (or maybe it's Tomato's https-server?!).
BUT: You can enable the HTTP webinterface over Telnet 8)

1) Login as root per telnet:
Code: Select all
$ telnet

Connected to
Escape character is '^]'.
PBS1 login: root

2) Enable HTTP:
Code: Select all
$ nvram set http_enable=1
$ nvram commit

This changes the setting and stores it back in the non-volatile memory (nvram).
Afterwards reboot to apply the changes:
Code: Select all
$ reboot

Now you should be able to access Tomato's webinterface over "http://" and deal with the SSL problem later.

Firefox 33.0 won't open a specific local application: Error code: sec_error_invalid_key
