HTTPS connection to ISY throws errors as Turn on TLS in browsers

Recommended Posts

I have installed my server's CA signed cert and root from CA on ISY's CA certificate.


But when i try accesing through HTTPS, i get the following error. 


what do i miss ?





Turn on TLS 1.0, TLS 1.1, and TLS 1.2 in Advanced settings and try connecting to https://mypreciousserver.com again. If this error persists, it is possible that this site uses an unsupported protocol or cipher suite such as RC4 (link for the details), which is not considered secure. Please contact your site administrator.

Hi KDBugger,


This makes no sense whatsoever. Are you certain you are going to the local (not remote) https port on ISY? If that works, then you can try the remote.


Also, make sure you have TLS 1.2 and Strength of All set for HTTPS Server:



With kind regards,
