Seeing “Server connection failed” when opening Voicemod? Check the service and your connection before changing Windows security settings.
First, check Voicemod’s status
Visit the Voicemod status page. If a service issue is listed, wait for it to be resolved and try again.
Try these connection checks
- Confirm your internet connection. Open another website. If possible, try another network to see whether the error is specific to your current connection.
- Update Voicemod. Install the latest version, then restart the app.
- Restart your computer. If you are on Windows, check for available updates in Settings → Windows Update, install them, and restart if prompted.
- Check managed network restrictions. If you use a VPN, proxy, or work or school network, ask its administrator whether it blocks Voicemod’s connection.
Install the ISRG Root X1 certificate on Windows
If Voicemod still cannot connect after the checks above, follow the certificate installation steps from the current Voicemod guide:
- Download ISRG Root X1 from Let’s Encrypt.
- Open the downloaded
isrgrootx1.derfile and select Install Certificate. - Select Local Machine, then Next. If Windows asks whether to allow the Windows host process to make changes, select Yes.
- Choose Place all certificates in the following store, then Browse.
- Select Trusted Root Certification Authorities and choose OK.
- Select Next, then Finish. Reopen Voicemod and try connecting again.
Download the certificate only from the letsencrypt.org link above. Installing a root certificate changes which certificate authorities Windows trusts.
