This typically happens when Larian's servers are down for maintenance, experiencing high traffic, or when something on your end — like your network or firewall — is blocking the connection.

When to Call a Professional

If you have tried all steps above and still receive Error Code 601 while other players can connect successfully, the issue may be specific to your ISP blocking Larian's server IP ranges. In this case, contact your Internet Service Provider and ask them to check for any firewall rules or port blocks affecting outbound UDP/TCP traffic. You can also submit a detailed support ticket directly to Larian Studios at support.larian.com, including your DxDiag report (Windows) or system logs, your geographic region, and the exact time the error occurred.

Frequently Asked Questions

What does Error Code 601 mean in Baldur's Gate 3?
Error Code 601 means Baldur's Gate 3 was unable to connect to Larian Studios' multiplayer servers. This is required for co-op sessions, whether you are hosting or joining a friend's game. The error can be caused by Larian server outages, your local network blocking the connection, a firewall or VPN interfering, or outdated game files.
Is Error Code 601 a server-side issue or a problem with my connection?
It can be either. Start by checking Larian's server status online. If the servers are confirmed down, it is a server-side issue and you simply need to wait. If servers appear operational and others are playing co-op fine, the issue is likely on your end — typically a firewall, VPN, DNS problem, or corrupted game file.
Can I play Baldur's Gate 3 solo while Error 601 is happening?
Yes. Error Code 601 only affects multiplayer co-op functionality. Your single-player campaign is fully offline and will work normally while Larian's servers are unavailable. You can continue your solo adventure and retry co-op once the error is resolved.
How long do Larian server outages usually last?
Scheduled maintenance windows for Baldur's Gate 3 servers are usually announced in advance on Larian's social media and typically last between 1 and 4 hours. Unplanned outages vary, but Larian's team generally resolves critical server issues within a few hours. Checking their Twitter/X account (@larianstudios) is the fastest way to get updates.
Does Error 601 affect all platforms or just PC?
Error Code 601 can occur on all platforms where Baldur's Gate 3 supports co-op, including PC (Steam and GOG), PlayStation 5, and Xbox Series X/S. The troubleshooting steps differ slightly by platform — PC users can flush DNS and check firewall settings, while console users should check their console's network settings, NAT type, and DNS configuration in the system network menu.
