No internet connection problem with add-on manager

[kodymoodley]

What's wrong?

There's an issue with the internet connection.

How can we reproduce the problem?

Go to Options > Add-ons

What's your environment?

• Operating system: Mac OSX Sonoma 14.2.1
• Orange version: 3.36.1 (but I experienced the same issue on 3.36.2 as well but it did not give the detailed stack trace of the error)
• How you installed Orange: .dmg downloaded from website (I do not experience this issue when installing via pip)
• Apple M1 Pro (2021)

A good reason to have an offline installer for add-ons ;) #6684

Same bug in Orange3-3.36.2-Miniconda-x86_64.exe, but just a pending installation process, no error message showed.

Thanks for the report. Did you always have this issue on that particular installation or does is pop-up intermittently? May I ask what are your local settings (language, which country)? No idea if these are connected, just a guess.

Actually it was strange. This issue suddenly popped up in the space of one evening. I was testing an add-on that I developed so I tried installing / reinstalling it several times from the add-on manager. It was working and then all of a sudden stopped in the space of 2 hours or so. Do you mean country and language settings on my laptop or in Orange? For the laptop Netherlands is the region and the primary language is English, secondary is Dutch.

Previously installed version was 3.32.0, no problems with it. I've multi-locale and multi-region machines, doesn't seems to be related. The first installation window pops up and then no action following (and no error message).

It is getting more and more confusing. I was not able to replicate it yet...

@kodymoodley, if I understand properly, it happens when the add-on dialog is being opened, so you do not even see a list?

@hydrastarmaster, are you able to see a list of add-ons? If I understood correct, installation of an add-on fails. Does it fail for any add-on? Try Educational for example, that is one of the smallest.

[markotoplak]

@kodymoodley, is your add-on public? If so, which one is it?

@hydrastarmaster, which add-ons did you install before getting the error? Or did this happen at the installation of your first add-on?

[markotoplak]

@kodymoodley, could perhaps copy the folder /Users/<your username>/Library/Caches/Orange/networkcache somewhere and then delete it?

Do not delete it straight away because within could be some clues to what is happening. Also, could you perhaps share it? (If you don't want to do it publickly, please send it to my username at gmail.)

Thanks!

@markotoplak Yes, I do not even see the list. It happens before.

@markotoplak Deleting /Users/<your username>/Library/Caches/Orange/networkcache solves the problem for me! There is only a requests.sqlite file inside. Do you want me to send that to you via gmail?

It seems that you got a malformed (or somehow incompatible) network request once. Yes, please send the file, so that we can at least replicate your issue and perhaps implement a workaround (I think cache should just be ignored in such cases).

3.36.2 freshly installed, so there are no previously installed add-on. I got the add-ons list. When I select any of them and start to install, the installation progress bar window pops up, and nothing appends. It goes pending with any of the add-ons... I've tried with Educational as you said, nothing different.
I just notice that when the add-ons installation starts, the pythonw.exe process get looped at the Start Address pythonw.exe!OPENSSL_Applink+0x480 and WINMM.dll!PlaySoundW+0xd70.

Similar issue here. I open Add-Ons, but before the list even populates, it says there was an issue with the internet connection:

I don't think it's an issue with my internet, since I can load files from a URL just fine. I installed this a couple weeks ago through mamba (or maybe conda) onto Ubuntu 23.10.
