Allo there, Unfortunately it happens and sometimes an error code isn't given. It could be anything from a small hiccup on your network or an ISP fault. If it keeps happening I'd suggest talking to your ISP and see if anything is happening on your line and their network or if they're doing any work somewhere. You should also refer to the following resource for guidance on Network Troubleshooting. [url]https://www.bungie.net/en/Support/Troubleshoot?oid=12915[/url]
