How can I troubleshoot network connectivity issues that might be causing the bootstrap download error?

First, check your internet connection. Ensure you have a stable and active connection. Try restarting your router and modem. If using Wi-Fi, try connecting with an Ethernet cable to rule out wireless interference. You can also test your internet speed to ensure it's sufficient for downloading the Runelite bootstrap. Temporarily disabling VPNs or proxies can also help.
