Internet traffic not getting routed through configured proxy settings

[Galphat]

This issue occurs in office network only.
After checking wth office support team they suggested to reach Eclipse support team since it was observed that internet traffic was not getting routed via configured proxy in Eclipse.
Eclipse version used:- 2021-12 (4.22.0)

Two things:

• Please report your OS as proxy support implementation differ between OSes
• Please try latest Eclipse version (2023-06) as 2021-12 is no longer supported

It looks like windows. Shouldn’t the entries be check marked to be used?

Native on Windows means "use Internet settings as configured in system control". However, I have seen that not working quite often on company machines myself, therefore I always recommend to use "manual". It will look the same, but you then have to set the checkboxes and all the entries for user/password yourself. Also you may want to add *.yourcompany.com" to the exceptions.

If anyone wants to investigate why this doesn't work with native: My main assumptions are

• "native" is interpreted as "don't use a proxy" somewhere in the code
• the actual native settings are too complex to fully use them in the Java code somehow (e.g. our company has a proxy configuration driven by a *.pac file in system control, which is in fact Javascript that dynamically calculates the proxy address based on location and who knows what).

Bonus answer for anyone running into this at a later point of time: If your company uses an authenticating centralized proxy (with NTLM authentication based on your Windows account credentials), then please use a local configuration-less proxy like px to get rid of the authentication hazzle. px will authenticate on your behalf, using the active Windows session.
