Solving certificate problem behind firewall/VPN

[antoniopaolini]

I tried to install denops plugin (to use bufpreview.vim), but it didn't works.
I received error Server stopped 4 times ...d to avoid infinity restart loop.

After a little bit of tinkering I started vim verbose with a log file, with the command vim -V9myVim.log and I got the complete error:

Messages maintainer: The Vim Project
[denops] error: JSR package manifest for '@lambdalisue/workerio' failed to load. Import 'https://jsr.io/@lambdalisue/workerio/meta.json' failed: error sending request for url (https://jsr.io/@lambdalisue/workerio/meta.json): client error (Connect): invalid peer certificate: UnknownIssuer

[denops] Server stopped (1). Restarting...
....[three more times]....
[denops] Server stopped 4 times ...d to avoid infinity restart loop.

I thought the problem should be the security software we use at work (if I check TLS certificate in the browser for jsr website I see all signed by Zscaler).
I found this website then I tried the last way (I'm in windows 11). IT WORKS!!!

Then I added in my vimrc the following line:

let $DENO_TLS_CA_STORE='system'

Then it works like a charm.

I did it in the best way? Any suggestion?

I write here because I didn't found anything on the web that helped me; I hope this will be helpful for everyone with my same troubles.

Thanks for sharing your Tips 🎉 I didn't know DENO_TLS_CA_STORE environment variable.

It seems that variable has introduced from Deno 1.13
