Error Websocket and SSL certificate on custom port. "SEC_ERROR_UNKNOWN_ISSUER".
I have developed a websocket app, it have SSL encryption and run behind a custom port. Firefox block the connection tought certificate is verified by ESET, and show me SEC_ERROR_UNKNOWN_ISSUER error. I have no problem on port 443. Can u help me ?
Hmm, ESET is intercepting connections on a custom port but not on port 443? Is that a setting in the ESET control panel, because normally they intercept both 80 and 443 by default. I hadn't thought about other ports. I guess my inclination would be to suggest to temporary turn off ESET scanning your web connections.
