OWS using System Proxy
Hello,
first thanks for your work on OWS.
I have found a problem with OWS using the System Proxy on Windows. In my test an application fails to start.
If I understand the logs correctly OWS reads the System Proxy settings correctly.
In the settings there is a list of addresses defined as proxy bypass.
In this it is 10.* and some more. The application that should start is hosted internally at https://10.240.58.240:443/...
When I try to start the application apparently OWS tries to reach out for the server using the proxy. At least it logs "Proxies found for ..." and shows the resolved IP for the configured proxy.
This means it does not read or uses the list of bypass addresses for the proxy.
Greetings
Paul

Re: OWS using System Proxy
Hi
Thanks for using OWS.
In case of System Proxy OWS will pick up the settings from the LAN settings presuming Windows OS.
To understand your issue better can you please attach the screen shot of your LAN Settings:
Also please send the logs.
I will try to reproduce your issue and investigate it.
Thanks
Janak

Hi,
here is the screenshot from the proxy settings.

Down below are the logs from the OWS console. I have taken some things out of the log that are internal.
Thanks for your help.

Re: OWS using System Proxy
Hi,
i guess i just found out the problem myself. In the proxy settings there is a box checked that the system should use the same for all protocols.
Apparently OWS does not understand this settings correctly. In the logs posted before you can see the proxy is only set for http.
Greetings

Re: OWS using System Proxy
Yes right. I was going to ask you about Advance setting where you apply the proxy to a particular protocol.

Re: OWS using System Proxy
Also if you notice in your LAN settings you have selected Automatically Detect Settings. It says this may interfere with Manual Setting and so must be disabled for manual setting to take effect. Please try your app after disabling it and see if it works as expected.

Re: OWS using System Proxy
I have checked it with disabled automatic selection, but it does not change anything in the behaviour.
I guess it is a problem with OWS not correctly detecting the option to use this proxy for https too.

Re: OWS using System Proxy
Hi,
Just to confirm:
Just to confirm:
- What is your local address?
- Your app is hosted at https://10.240.58.240:443/
- You have specified a proxy server and checked bypass proxy server for local addresses
- You have specifed that the same proxy to be used for all protocols.
- Did you specify any exceptions (See picture below):
- What happens if you put https://10.240.58.240:443/ in the Exception list, shut down the proxy and run the app? The app should still run as the proxy is not supposed to be used for the addresses in the exception list.

Re: OWS using System Proxy
Hi,
1. My local adress is 10.2.10.84 .
2. Yes. It is the viewer application for a Dell iDRAC console.
3. Yes shown in the attached screenshot.
4. Yes shown in the attached screenshot.
5. Yes there are many. Mostly for local adresses like 10* or 192.168.* and some external resources.
6. I have tested it without shutting down the proxy as I cant do that. But when I added the exact IP to the exclusions it instantly worked.
Below is a bit of the log. I guess OWS matches the exact IP here and excludes it. Apparently it does not match 10.* from the exclusion list.

Re: OWS using System Proxy
I am not sure if 10.* is a valid wildcard spec for an IP address. May be you can try 10.*.*.*?
I did some search and found this: https://docs.microsoft.com/en-us/previo ... dfrom=MSDN

Re: OWS using System Proxy
I have tried it but that does not change the behavior. According to the logs OWS still does not match the IP.
My guess is that OWS does not match with the wildcard IP address.

Re: OWS using System Proxy
We have taken a look at this during the last week.
The wildcard syntax which is currently accepted by Windows is not trivial.
It is possible to implement this feature. But since this will take a considerable amount of effort we will currently not prioritize this.
If this feature is a must have for your company you have the option to sponsor the development.
