How to configure a proxyserver

[jacquesschenk]

I'm using 2 proxy servers for communication with the internet, one system wide proxy with authentication and one without authentication.
When importing logfiles, the import fails, the error says incompatible files, but the log says network error.
Although I do not understand the need for the application to access the internet, If it is a legitimate attempt, I need to somehow specify the proxy IP address and port. Where/how do I do this?

[Naveenv26]

Git often fails to import log files through a dual-proxy setup because it defaults to system environment variables that may not include your authenticated credentials, causing the network error to be misinterpreted as a file incompatibility. To resolve this specifically for Git, you must explicitly map your authenticated proxy in the global configuration by running the command

git config --global http.proxy http://username:password@proxy_ip:port,

ensuring any special characters in your password (like @ or #) are URL-encoded. This forces Git to bypass the unauthenticated system default and use the correct gateway for its network requests, which are typically required for resolving commit metadata or external references during log processing.

[jacquesschenk]

Thanks for your respons!
To me, the problem seems to be located in the application itself, not in GIT.
The authenticating proxy cannot be used since it authenticates with entra-id, no password for the account is known to the user who logs on with a smartcard or Windows Hello for Business.
For that reason we also have a proxy which does not require authentication, this is the one I want to use if needed.
But as said, it seems the problem is caused by the way the Open Dronelog application is handling internet traffic across a proxy.

[Naveenv26]

Since Open Dronelog likely relies on the standard Windows network stack,
it is automatically defaulting to your system-wide Entra-ID proxy, which fails because the application cannot handle the Smartcard or Windows Hello authentication handshake. When the authenticated proxy blocks the request,
it sends back an HTML login page or an error message that the application's parser misinterprets as an "incompatible" log file format.

To resolve this, you can bypass the system defaults by launching the application via a batch script that explicitly sets the http_proxy and https_proxy environment variables to your unauthenticated proxy's IP and port, ensuring the app routes its traffic through the open gateway instead.

@jacquesschenk The DJI log files are encrypted, not standard text file. the application must request the decryption key for the file from DJI's server if the key is not cached in storage (i.e. re-importing the same file), as documented in the README. So for initial import of log files, internet access is a requirement. this is not a limitation or illegitimate access attempt, this is how it needs to be done.

@arpanghosh8453
I tried the suggestion of creating the environment variables and starting the application form that shell after that
I executed the following commands:
set HTTP_PROXY=http://xx.xx.xx.xx:8080
set HTTPS_PROXY=https://xx.xx.xx.xx:8080
set http_proxy=http://xx.xx.xx.xx:8080
set https_proxy=https://xx.xx.xx.xx:8080
and then started the application, but I got the same errors about not being able to connect to the website.

Then I tried to do the same from a powershell script:
$env:HTTP_PROXY="http://xx.xx.xx.xx:8080"
$env:HTTPS_PROXY="https://xx.xx.xx.xx:8080"
$env:http_proxy="http://xx.xx.xx.xx:8080"
$env:https_proxy="https://xx.xx.xx.xx:8080"
$env:DEBUG="http,https,net"
cd "C:\Users\J\AppData\Local\Open DroneLog"
.\open-dronelog.exe

The application started fine, but again no connection to the website
Do you have any other suggestions?
Would it be an option to include the poxy settings in the app settings?
For a lot of other applications I use, this works fine.

Again: the errors in the log:

When going to https://dev.dji.com:443 in my browser with the same proxy, the website shows up fine.

@jacquesschenk

The keychain fetch uses ureq in the dji_log_parser crate, which does not honor environment proxy settings by default, so the request goes out as a raw TCP connection.

try using a per‑process proxy tool on Windows (Proxifier, ProxyCap, or similar). These hook the process and route all TCP through your proxy even if the app is not proxy‑aware.

[jacquesschenk]

This could be a kind of workaround, not a solution
My suggestion would be to either honor the environment variables or even better implement a proxy setting in the settings page.
(Proxifier, seems to work ok, but it is not allowed by company policy and I prefer a simple setting to another tool which requires updates etc.)

[arpanghosh8453]

@jacquesschenk acknowledged. I agree this is a workaround and a limitation. I did not consider this, but it makes sense for a company environment behind CGnet. I will look into this in the future. I don't have a proxy server setup, so testing would be a little tricky.

[jacquesschenk]

@arpanghosh8453
No problem, I can test for you if you want, but you can also install a proxyserver on you w11 workstation or linux device like a NAS
For W11 this could be Squid for Windows ((config via config file) or CCproxy which is limited but gui based and perfect for fast tests.
Looking forward to your resolution!
Thanks a lot!

[arpanghosh8453]

@jacquesschenk Give this version a try when ready : https://github.com/arpanghosh8453/open-dronelog/releases/tag/3.3.0

This is using the reqwest library and should respect ENV variables when properly set via http_proxy, HTTP_PROXY https_proxy, and HTTPS_PROXY : https://github.com/arpanghosh8453/open-dronelog/releases/tag/3.3.0

Let me know if this works for you after upgrading.

@jacquesschenk Does it still work with Proxifier? How long it hangs? Can you trace the request if it's hitting the proxy server or not?

Finally I found the solution to the problem: the environment variable needs to be defined as follows: Set https_proxy=http://xx.xx.xx.xxx:8080 so use https_proxy (with an s) as the variable name and in the proxy server address use http, NOT https Thanks a lot guys, it is working now!!

You are welcome @jacquesschenk , thank you for testing and providing the logs!
