How to Fix a Better MC [BMC6] Server That Keeps Crashing
LunaPixelStudios' own Better MC troubleshooting guide names one cause above all others for BMC6: the pack updates frequently, and a client even one version off from the server refuses to connect entirely — not a crash in the usual sense, but it reads like one.
See the Better MC [BMC6] pack page for sizing before you chase anything else.
1. Client and server version mismatch
This is the pack's own stated most-common issue: BMC6 updates frequently, and the CurseForge client version has to match the server's installed version exactly — even a minor difference prevents connection. If the server rejects every player, check this first before anything else.
2. RAM below 8-10 GB
220+ mods and heavy world generation put BMC6 in the same RAM range as other large Better MC entries — 8-10 GB is the commonly cited floor. Below that, expect the usual cascading instability rather than one clean error.
3. Check the official troubleshooting guide first
LunaPixelStudios maintains a dedicated troubleshooting resource at better-mc.com for crashes, lag and common problems — worth checking before filing a bug, since BMC6's fast release cadence means issues get documented and fixed quickly.
FAQ
Why does my server reject every connection attempt?+
LunaPixelStudios' own guidance calls this the most common BMC6 issue: the CurseForge client version has to exactly match what's installed on the server. BMC6 updates frequently, so a client that auto-updated while the server didn't (or vice versa) will fail to connect every time.
How much RAM does BMC6 need?+
With 220+ mods and heavy world generation, 8-10 GB is the commonly cited floor for packs in the Better MC series at this scale.
Where does the Better MC team document troubleshooting directly?+
They maintain an official troubleshooting guide at better-mc.com covering crashes, lag and common problems, plus a Discord and GitHub for anything not already listed there.
