While now it appears that all of my services are running (after following all the help here so far) I am still ending up with the same bad gateway error.
Question 1: I created the self-signed certificate…and that doesn’t seem to be the problem. I can get the bad gateway over both http and https with the normal browser warnings. That shouldn’t be the problem, right?
Question 2: I’m concerned that the third link talks about “server blocks” which I felt like mostly didn’t apply to my install. This little server will be doing nothing else but RapidSCADA, so I presumed that simply copying the default file into the sites-available folder was enough. Do I need to define server blocks as well?
I know what it means now 🙂
My point is, as someone who has never used a dotnet library on linux, I had completely missed/overlooked/ignored any subtle clue that I should end up with not 1 but 2 dotnet libraries installed. I don’t usually, but I did in this case. It’s easy (though maybe not smart) to look at that and think it’s referring to the same thing by two names.
So, it might be helpful to people coming in with fresh eyes to know that the correct result is two dotnet libraries on the RapidSCADA install page. The rest seemed explicit enough.
Once the user goes to a Microsoft page, it gets a little sketchy how the two relate anyway. Nonetheless, installing both libraries as I should have fixed my stuck service. That got me another step along the way.
I installed both components, once again, I recommend that the install docs get updated to say that the installation should have 2 running before moving on.
All of the services are running now. But, sadly, I still get a bad gateway / 502 error.
scadaagent6.service. loaded active running Rapid SCADA Agent scadacomm6.service loaded active running Rapid SCADA Communicator scadaserver6.service loaded active running Rapid SCADA Server scadaweb6.service loaded active running Rapid SCADA WebstationOkay, so there is an issue. The installation instructions should be updated to include that information. If both are required, there should be a note to describe that at https://rapidscada.net/docs/en/latest/installation/install-linux
It points to a this page (in my case) https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu-install?pivots=os-linux-ubuntu-2204&tabs=dotnet8 which really doesn’t tell me which to do… So I rolled the dice.
Let me get that installed.
Looks like I stepped away for a minute…
In any case, I have followed the steps that you originally gave me and then what you had given to the other user.
- It appears that I have dotnet installed at the 8.x.x version. No SDKs, though, runtime only, if that matters.
- According to the logs, nginx seems to be serving, but only the bad gateways.
- There isn’t a log for ScadaWeb, since it won’t start, but ScadaServer and ScadaComm both seem to be running according to their logs. No idea what to look for, but generally they seem to be “doing things.”
Here’s the Nginx log:

My current proxy_pass is set to 10008… which came with the rapidscada archive. So that should be changed to 5000?
Well… there’s the problem. There IS no directory for ScadaWeb. I take that to mean it isn’t started… or there’s a permissions issue in writing to that location. Once again, this is a fresh install of Ubuntu Server 22.04 and following the install docs as carefully as I could.
https://rapidscada.net/docs/en/latest/installation/install-linux
Which said nothing about port 5000 (step #5) unless I totally missed it. I’m guessing with that section in the proxy_pass will get me closer if not solve the problem.
