AnkiConnect install failure due to a security proxy, looking for a bypass

Anki Add-ons

Hi, today I installed Anki and tried to get AnkiConnect installed, but failed with following error message:

One or more errors occurred:

2055492159: Please check your internet connection.

HTTPSConnectionPool(host=‘ankiweb.net’,

port=443): Max retries exceeded with url: / shared/download/2055492159? v=2.1&p=250201 (Caused by SSLError(SSLCert VerificationError (1, '[SSL:

CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate in certificate chain Lssl.c:1129)')))

I believed this is due to the company’s security proxy and cross-checked this with Grok and Gemini. This is indeed because of that.
They suggested to do manual add-on install, downloading the add-on file from a website or networks instead of let Anki to connect AnkiWeb.
I checked out the AnkiConnect download page but it seems there’s no download file directly available, only providing code for the add-on.

Gemini also said try with below CURL, and I tried below:

curl -L -o AnkiConnect.ankiaddon https://ankiweb.net/shared/download/2055492159

And I managed to get an Anki file named “AnkiConnect.ankiaddon”, but it’s giving me an error message like this when I tried it:

Error installing ⁨AnkiConnect.ankiaddon⁩: ⁨Corrupt add-on file.⁩

Please report this to the respective add-on author(s).

And now I don’t know what to do. Where can I find a direct download to the AnkiConnect file?

I know that having my own device would be the optimal solution but that’s not an option ATM.
Would appreciate any advice.

Edit: Forgot to mention the version and device details, I use Apple Silicon Macbook and just downloaded the latest version of Anki today, it’s Version ⁨25.02.1

You should revert to Anki version 25.02 (or whatever version you upgraded from) for the time being. Security fixes in the 25.02.1 patch version are likely interfering with the add-on.

If you install from a zip/ankiaddon file, the package has to contain a manifest.json file. You can add this manifest.json to the zip, then re-package it and install to work around the issue:

{"package": "ankiconnect", "name": "AnkiConnect"}

I developed an old AnkiConnect downloader earlier, I think the latest AnkiConnect can be downloaded directly from here. add-on file: AnkiConnect.fork.by.Shige.ankiaddon

Download the .ankiaddon file and open it with a double-click, or install it from the “Install from file” menu in the Anki add-ons management screen. (Please note that you cannot install the file by dragging and dropping it into Anki).

And HTTPS problems may be solved by using this add-on.
add-on file: Enable.HTTPS.interception.with.foreign.SSL.certificates.ankiaddon
add-on page: :shield:Enable HTTPS interception with foreign SSL certificates (Reupload by Shigeඞ)
