ERS – Expert Remote system 2021 testing...
Workin on local net ok. (Rpi server).
But trying to connect from an other location over the internet , dont get any connection. Why can that be?
Should there be any setting in the 4Grouter? Ports to be opened, etc? Nothing about that in the ERS manual.
Any hints?

Must add: today I tried the web-client and that worked. So the SUNSDR is active up and working.
Problem is with ESDR3 remote tab, that do not connect over internet. worked fine locally. (ESR3 Beta 1.0.1 at the moment. 03. had problem with PA and EXt port).

Had the same issue (see my recent post)
Problem was that my ISP gave me a private IP. Asked for a public IP and the problem disappeared.

Hope this will help you!
