VeniceEXT HTTPS Request fails on Linux (Certificate validation error)

[smrb]

Hello,

following line of code does not work on my linux hosted servers.
res = Net:GetHTTP("https://gitlab.com/n4gi0s/vu-mapvote/-/raw/master/mod.json");

The error I'm getting:
[VeniceEXT] HTTP Request failed with error ‘Certificate validation error: Failed to verify certificate chain: CA not trusted’.

Afaik wine should use the certificates installed on the linux machine just fine, I don't know why it doesn't do it in this case. Just another quirk of hosting vu on linux, that should maybe investigated later.

Additional Information:
System: Ubuntu 20.04 64bit
Running latest wine.

Here is the mod where I encountered the problem: https://gitlab.com/n4gi0s/vu-mapvote
The author tried to fix this by deactivating cert verification like this:

   options = HttpOptions({['verifyCertificate']=false}); --ignore cert for wine users
   res = Net:GetHTTP("https://gitlab.com/n4gi0s/vu-mapvote/-/raw/master/mod.json", options);

This did not help, this is why I suspect a problem with VeniceEXT / the lua interface when running wine.

This should be fixed in build 17485. VU comes with a pre-bundled set of CA certificates that it uses for validation (which was probably outdated). You can override the one it uses by passing the -cacert parameter with a path to a custom CA bundle.
