I am trying to figure out what type of port forwarding I need to do on the network to make Simpl Debugger work with VC-4.
This is not a question on how to use SIMPL Debugger with VC-4 on a local network.
This is a question on how to use SIMPL Debugger with VC-4?from a remote location via port forwarding.
?
I successfully forwarded the usual ports such as 443 and 41796 (so I can remotely get into the VC-4 web-interface and also use CrestronGo)... all that works fine.
Where I am getting stuck is when I try to remotely connect with Simpl Debugger. I am forwarding port 49300 and I am getting an error that says:
?
"The VC4 server rejected the web connection due to one of the following:
- the address has an invalid room id
- the address has an invalid token
- the room is not running
- the room is not in debugging mode
The SIMPL debugger cannot continue."
?
I know all of the above are good because this works perfectly fine when I am on the local network.
I am getting this error only when I try to remote in via port forwarding.
?
Now, I understand that VC-4 Debugger uses websockets (I have limited knowledge of this underlying technology) but as far as I know, Websockets runs on top of HTTP which in turn runs on top of TCP, no?
So in theory, I should still be able to have remote access by forwarding the appropriate TCP port.
?
I want port forwarding to work mainly for three reasons:
1- Some of my customers cannot give me VPN access but will give me temporary port forwarding. Not ideal, but has worked out fine for me through the years.
2- Sometimes I provide remote support using AnyDesk, which allows me to do TCP tunneling, which in turn allows me to connect to the remote processor straight from my machine. I have been doing this forever with appliance boxes.
2- I like to run VC-4 in a guest virtual machine environment and I need to establish the proper port forwarding between the guest and the host. I was able to make everything else work except Simpl Debugger (which is a big deal).
?
I know this group has some really bright minds. Anybody ran into this before?
