RV042 weak ephemeral Diffie-Hellman key

[Ken Wiens]

SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. Error code: SSL_ERROR_WEAK_SERVER_EPHEMERAL_DH_KEY

I can't access the router because of this issue, so how do I fix this?

Hello Ken,

1. Open the IP of the router via Internet Explorer. If you continue to receive this error, add the IP in the trusted websites.

2. Change the WebGUI access method from HTTPS to HTTP so you can open the GUI with other browsers as well.

This usually solves the issue, but if you continue to experience it, please call our line at:
