HTTPS request internal error for the first one

[Bluelich]

Description

• When using VPN (Quantumult X) together with Proxyman SSL Proxying, the first HTTPS request after startup always fails with an internal error (code 999).
• Sending the exact same request again (using Proxyman’s Repeat feature) succeeds with HTTP 200, which - confirms the request itself is valid and unchanged.
• This behavior reproduces every time after restarting Proxyman.

Steps to Reproduce

1. Enable VPN (Quantumult X) (without https mimt/ rewrite and so on, proxy for xxxx.com is DIRECT)
2. Launch Proxyman on macOS
3. Enable SSL Proxying with wildcard rule: *.xxxx.com （Proxyman）
4. Launch the iOS app on iPhone
5. Trigger an HTTPS request → This first request fails
6. Select the failed request in Proxyman and click Repeat → Repeat succeeds
7. Quit Proxyman
8. Relaunch Proxyman and repeat steps 4–6

Current Behavior

1. First HTTPS request after each Proxyman launch
   • Status: Internal Error
   • Code: 999
2. repeat the request
   • Status: Completed
   • Code: 200
3. After the first failure, all subsequent requests work normally

Expected Behavior

• The first HTTPS request after startup should succeed
• Behavior should be consistent across the requests

Environment

1. vpn quantumult X 1.5.4
2. macOS: Tahoe 26.0.1, Proxyman root certificate installed and trusted
3. Proxyman: Version 6.3.0 (60300)
4. iPhone 12： iOS 18.6.2, Proxyman trusted profile installed
5. SSL Proxying rule: *.xxxx.com
