I have been using Copilot in VS Code for a while, and now I’m trying to test AI in Toad. Since I only have a perpetual license, I can test it for the next few weeks to decide whether I like AI with Toad or not.
When I connect Toad to my account, I get the error: “self-signed certificate in certificate chain.” In VS Code, there are options to fix this. This error is a known issue in VS Code caused by corporate firewalls, which I cannot bypass.
Previously in VS Code, I used the extension win-ca (Visual Studio Marketplace) to resolve this issue. Now, the Copilot extension includes the same setting, so I no longer need that extension. I’m sharing this just to give you some context.
Here’s the error log for reference:
