Trying to setup dynamic DNS forwarding through my router with HTTPS. Router says port is open, nmap says port is open, but the browser reports "Site can't be reached" and <UNC> "unexpectedly closed the connection." and finally ERR_CONNECTION_CLOSED. Error message in ISY reports "System -170001 [TCP-Conn] -6/-140002, Portal-Dispatch". This error does not appear in the ISY error list at "ISY-99i/ISY-26 INSTEON:Errors And Error Messages". Any clues? I have tried adding the WEB/xxxx paths after the UNC without effect. Thanks!
