VSCode extension giving "Error: unable to get local issuer certificate" when expanding folders under tenant

First time ISC engineer here. I have created a Personal Access Token in my sandbox environment with sp:scopes:all. I have installed the SailPoint Identity Security Cloud vscode extension and created a connection to my sandbox environment, providing client ID and secret. I am able to expand the tenant and can see folders underneath (Sources/Transforms/…/Campaigns at bottom). When I attempt to expand any of the folders I am getting “Error: unable to get local issuer certificate”. I have confirmed my company certificate is available in current user Trusted Root Certification Authorities. I have no issues browsing to my sandbox environment via Chrome or Edge. I can connect via api call through powershell authenticating with PAT without issue.

I attempted each of these to no avail. Exporting the certificate from my Trusted Root Certification Authorities (verified it is the same certificate used for web browsing) and creating NODE_EXTRA_CA_CERTS system variable and pointing it at the .crt (PEM format) file location. Also tried proxyStrictSSL false to no avail. I am using the latest extension (just installed it last Friday).

I will contact my company’s network team for assistance tomorrow. Assuming that all necessary certificates are correctly installed and there are no VS Code options I can explore that do not violate my company’s security policy is there any alternative for this extension?
