I want to use a custom CA Certificate with a network proxy

[MrRanjanRavi]

Expected Behavior

Insomina should be allowed to be configured with other proxy tools like the Postman tool.

Actual Behavior

After configuring the proxy and adding the PEM certification, getting an ‘Error: SSL connects error’. We are only able to capture and run the HTTP request and not the HTTPS.

Reproduction Steps

1. Go to preferences >> General >> Network Proxy
2. Set the proxy for HTTP and HTTPS (eg. localhost:8085)
3. Setup the same proxy to any listener tool like Fiddler, zap, burp etc.
4. Go to Scratchpad >> Settings >> Certificates
5. Upload the PEM file of the listener tool
6. Create a request and run
7. Ensure the same request is captured by the proxy tool as well.

Is there an existing issue for this?

@MrRanjanRavi Can you try this operation with Insomnia 8.6? We shipped several SSL improvements.

The issue remains the same with 8.6.1

@MrRanjanRavi I can't reproduce this issue with 8.6.1. Did you follow the steps at https://docs.telerik.com/fiddler/configure-fiddler/tasks/trustfiddlerrootcert to trust the FiddleRoot Certificate first?

BTW, did you enable the ssl certificate verification option on Postman?
