[BUG] Click To Tune is not working with rig-bridge 1.2.0 and SmartSDR (Flex radio)

[williamscody]

Describe the Bug

rig-bridge is connecting fine through the UI setup (localhost:5555) and I can see Rig Control in OHC tracking my frequency changes. However, clicking on frequencies in the OHC DX Cluster window doesn't tune the radio. I see activity in rig-bridge (below), but no click-to-tune is happening (it is enabled in OHC Rig Control settings).

To Reproduce

1. Build an executable per the rig-bridge README (I did macOS)
2. Launch rig-bridge
3. Visit http://localhost:5555 and configure SmartSDR settings for your radio
4. Enable "Click to tune" in OHC
5. In OHC, witness a successful connection, and frequency tracking under RIG CONTROL
6. Click on any frequency in the DX Cluster pane, and the radio does not change frequency

Expected Behavior

Click on a frequency and the radio should tune to that frequency.

Environment

• OS: macOS Tahoe
• Browser: Safari 26.3.1
• Node.js Version: 23.6.0
• OpenHamClock Version: 26.1.3
• Running As: Local Ubuntu Server

Update: I tried Rigctld / Hamlib as an alternate connection to my rig, and that doesn't work either. It used to prior to the current release.

@williamscody — this is very likely the same root cause we just identified and fixed in #707: a CORS whitelist issue.

Reads (frequency tracking) work because SSE/GET requests don't trigger browser CORS preflight. But writes (click-to-tune, PTT) send POST requests with custom auth headers, which the browser silently blocks if your OHC origin port isn't in rig-bridge's whitelist.

Quick fix — what port is your OHC running on? Check the URL in your browser when you open OpenHamClock (e.g., http://localhost:3000 or http://localhost:8080). Then add it to your rig-bridge-config.json:

{
  "corsOrigins": "http://localhost:YOUR_PORT"
}

Restart rig-bridge and click-to-tune should start working.

We've already pushed fixes to add common ports (3000, 3001, 8080, 8443) to the default whitelist, plus CORS rejections now log to the rig-bridge console so they're no longer invisible. This is on the Staging branch.

I see, since you are running on the web, you can try to test it on our staging site at stagingbranch26.openhamclock.com and report back if it is fixed... this will be pushed to main on Tuesday
