So far, we have received reports from customers using Bitdefender (using Windows as the operating system) and you can find instructions below to mitigate. ## Bitdefender Bitdefender's _Encrypted web scan_ feature is part of their _Online Threat Prevention_, which requires all responses to be finished before getting scanned. As we're streaming the response, the feature is not able to detect any threat on the go and therefore the build logs are loading indefinitely. To prevent this and have your build logs appear as expected, there are two possibilities to mitigate: ### Add an exception for Vercel 1. Open Bitdefender Total Security 2. Open **Protection** on the left menu bar 3. Click **Settings** in the **Online Threat Prevention** card 4. Click **Manage Exceptions** and add `vercel.com` as an Exception ### Disable Encrypted web scan 1. Open Bitdefender Total Security 2. Open **Protection** on the left menu bar 3. Click **Settings** in the **Online Threat Prevention** card 4. Disable the toggle button next to _Encrypted web scan_ ## Other Antivirus Software If you encounter a similar issue with a different software, please review any possible settings in your antivirus software containing "Web inspection", "HTTPS inspection", "Deep packet inspection" or similar or if you have the ability to allowlist certain websites directly (if so, you may allowlist `vercel.com`). You should also first try a different computer or device without the antivirus software installed to confirm if this software is responsible for it or not. If you're not able to find any settings related to this and it works after disabling/uninstalling your antivirus software, please reach out to your antivirus vendor for further assistance. If you're able to reproduce the issue without any antivirus software, then please reach out to us through [vercel.com/help](https://vercel.com/help).
