Proxy configuration not saved #7573

matthjes · 2018-05-07T10:25:03Z

Hi,

I'm working behind a corporate proxy, so I need to configure the proxy in the IDE. However, when I enter the proxy credentials, close the configuration window, and reopen it again, the credentials are missing. This also happens when I enter the credentials directly into the preferences.txt: as soon as I restart the IDE the credentials get erased.

This happens with version 1.8.5 and 1.9.0 beta.

This problem is also described in this thread: https://forum.arduino.cc/index.php?topic=392432.0

Hi @matthjes ,
it looks quite strange; a possible explanation is that you don't have write access to your user-wide preferences.txt (which lives in Arduino15 folder, the exact location depends on the operating system in use, C:\Users\username\AppData\Local\Arduino15 in case you are in Windows).
Just to make sure, if you change any other property (like the sketchbook location or the verbosity) are they getting saved on restart?

@matthjes are you still having this problem? We're still waiting for you to provide the information requested by facchinm.

I can reproduce this problem with Arduino IDE 1.8.7 hourly build 2018/10/24 04:33 and Arduino 1.9.0-beta build 87 using Windows 10.

Delete or rename your preferences.txt file to simulate a fresh installation. You can find the location of preferences.txt by clicking the link at the line following [File > Preferences > More preferences can be edited directly in the file.
File > Preferences
Click on the "Network" tab.
Select "Manual Proxy Configuration"
Enter something in all the input fields.
Click "OK"
File > Preferences
Click on the "Network" tab. The Manual Proxy Configuration Username and Password fields are empty.
Click "OK"
File > Quit
Open preferences.txt. The proxy.manual.password and proxy.manual.username properties are blank.
Start the Arduino IDE.
File > Preferences
Click on the "Network" tab.
Select "Auto-detect proxy settings".
Enter something in all fields.
Click "OK"
File > Preferences
Click on the "Network" tab. The Auto-detect proxy settings Username and Password fields are still filled.
Click "OK"
File > Quit
Open preferences.txt. The proxy.manual.password and proxy.manual.username properties are set to the values you entered in the Auto-detect proxy settings Username and Password fields.
Start the Arduino IDE.
File > Preferences
Click on the "Network" tab.
Select "Manual Proxy Configuration"
Click "OK"
File > Preferences
Click on the "Network" tab. The Manual Proxy Configuration Username and Password fields are now filled with the values you entered in the Auto-detect proxy settings Username and Password fields.

So there is clearly a bug in the Manual Proxy Configuration system. There is no problem writing any other preference and even proxy.manual.hostname and proxy.manual.port work as expected.

It's also not clear whether it was intentional for Auto-detect proxy settings and Manual Proxy Configuration to share the same proxy.manual.username and proxy.manual.password properties or that's a bug.

I can confirm this behaviour on Win10, IDE 1.8.8
Auto-config writes and reads to the manual fieldes in preferences.txt.

Also behind a corporate firewal wall and must use a proxy with authentification. I tried several combinations in GUI and preferences.txt without success.

Does the auto configuration also look for the environment variables HTTP_PROXY or HTTPS_PROXY on Windows?

solarjoe · 2019-01-25T07:44:45Z

I can download the http://downloads.arduino.cc/packages/package_index.json from my browser and I tried to configure the Arduino IDE the same way, without luck.

When trying to update the boards list I get

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"

I noticed in another thread (#5887) that it could also show something like

Using proxy HTTP @ /192.168.0.254:3128
Caused by: java.io.IOException: Received invalid http status code from server: 416

This is the section from my perferences.txt:

proxy.manual.hostname=x.x.x.x
proxy.manual.password=xxxx
proxy.manual.port=8080
proxy.manual.type=HTTP
proxy.manual.username=xxxx
proxy.pac.url=
proxy.type=manual

solarjoe · 2019-01-25T08:09:00Z

Could it be related to this?

facchinm · 2019-01-25T08:27:34Z

@solarjoe it might indeed be the case. Since you are on Windows it's a bit tricky to modify that config on the fly but I'm preparing a PR so you can test it and report if jdk.http.auth.tunneling is the culprit.

Should fix arduino#7573 Based on the suggestions from https://stackoverflow.com/questions/41806422/java-web-start-unable-to-tunnel-through-proxy-since-java-8-update-111

facchinm · 2019-01-25T08:34:30Z

PR created here #8436 , binaries should be ready in an hour more or less.

solarjoe · 2019-01-25T08:47:45Z

I just tested this and it works when I add

-Djdk.http.auth.tunneling.disabledSchemes=""

to the file arduino.l4j.ini or arduino_deubg.l4j.ini where you can pass additional parameters, see
http://launch4j.sourceforge.net/docs.html#Additional_jvm_options

solarjoe · 2019-01-25T08:48:50Z

I was not testing the new binaries, just modified the installation I had (1.8.8).

facchinm · 2019-01-25T08:57:38Z

If you could test the PR binaries it would be better since every OS has its own different launcher and adding flags is a bit tricky in some of them (OSX for example)

solarjoe · 2019-01-25T12:25:04Z

Yes, that seems to fix it for me, but only if I enter the following parameters in the preferences.txt
before launching the IDE:

proxy.manual.password=abc
proxy.manual.username=def

These values are not saved when entered in the GUI, but they are read correctly from the file into the GUI if already present.

ThomasBe · 2019-02-01T10:50:03Z

I had the same issue and until 1.8.7 everything was fine. With 1.8.8. I try a lot to get my proxy settings working again.

By just adding the mentioned line into arduino_deubg.l4j.ini everything is fine with the same settings like with 1.8.7.

solarjoe · 2019-02-01T11:15:33Z

@ThomasBe, do you also see the issue with the proxy setting not being saved when you enter them in the UI?

ThomasBe · 2019-02-01T11:58:44Z

@solarjoe , I only use the "auto_proxy_part" and everything works regarding modyfing in GUI or via preferences.txt.

JorinL · 2019-02-04T22:07:40Z

With PR #8436 I have the following experience going through the steps from above:

Filling the manual proxy config with "abc" clicking ok and opening it again shows only hostname and port filled.
looking into the preferences.txt shows:

proxy.manual.hostname=
proxy.manual.password=
proxy.manual.port=
proxy.manual.type=HTTP
proxy.manual.username=
proxy.pac.url=
proxy.type=none

First thought caused by my job - I should not be able to fill in "abc" into a pure number field :-D
Event with a number in it only hostname and port is saved in the gui

Filling the auto proxy config with "abc" clicking ok and opening it again shows everything filled.
looking into the preferences.txt shows:

proxy.manual.hostname=
proxy.manual.password=
proxy.manual.port=
proxy.manual.type=HTTP
proxy.manual.username=
proxy.pac.url=
proxy.type=none

No Proxy shows me nothing special in the config but stays selected in the gui even after reopening

Thomseeen · 2019-04-04T09:23:02Z

Beeing on Unbuntu 18.04 with Arduino 1.8.9 I managed to make the IDE remember my proxy credentials by editing the preferences.txt but i still get the "HTTP/1.0 407 Proxy Authentication Required" error.

I just tested this and it works when I add

-Djdk.http.auth.tunneling.disabledSchemes=""

to the file arduino.l4j.ini or arduino_deubg.l4j.ini where you can pass additional parameters, see
http://launch4j.sourceforge.net/docs.html#Additional_jvm_options

Can someone help me find those .ini-files to add the needed launch parameters to my 1.8.9 installation?

solarjoe · 2019-04-04T16:05:15Z

Should be in the same folder as your Arduino IDE binary.

Thomseeen · 2019-04-05T07:35:48Z

On my Win10-machine, yes, under Ubuntu, sadly not...

facchinm · 2019-09-18T07:23:47Z

@solarjoe @JorinL @ThomasBe @Thomseeen @matthjes could you give a spin to latest IDE 1.8.10 and report if the proxies are still not applied?
#9023 is included and was meant to solve most of the downloads issues.

I checked 'my problems' with the latest version (1.8.10) and internet connection stuff works fine for me without any additional work around.

So I just entered my network settings using the automatic configuration via configuration url.

@TomasRoj thanks a lot for testing. I'm closing this as fixed, if it's not please comment here and we'll reopen it.

Hi @QGB. Arduino IDE 2.x uses a completely different preferences store from Arduino IDE 1.x. The preferences.txt file is completely ignored by Arduino IDE 2.x, so it is expected that the proxy configuration from that file has no effect on Arduino IDE 2.x.

You can configure the proxy of Arduino IDE 2.x by doing the following:

Select File > Preferences... from the Arduino IDE menus.
Click the "Network" tab.
Select the "Manual proxy configuration" radio button.
Configure proxy as needed for your network.
Click the OK button.

If you have any questions or problems, please post over on the Arduino Forum. I'll be glad to help you out over there:
