The Lost Era Modpack server hosting & setup guide

A server for The Lost Era Modpack needs Java 8. We'd start it on 8 GB of RAM (our Premium plan) and watch the memory as players join.

Designed for players of all skill levels to fully utilize modded content, be it Magic, Tech, and more.

Java needed	Java 8 for Minecraft 1.7.10 Java version chart.
Mods	Not countedThe pack uses ServerStarter, which downloads most of its mods when the server first starts, so Modrinth's file list doesn't show them. We picked the plan from the pack's tags instead.

The Lost Era Modpack server files

Yes, on CurseForge. Modrinth has no separate server pack for The Lost Era Modpack, but the authors publish one on CurseForge: LostEra-v1.6.10-(Server).zip, for The Lost Era 1.6.10 (June 21, 2026). That's the same version Modrinth has.

CurseForge lists it as an extra file rather than as that version's server pack, so installers that look for CurseForge's server pack won't find it: download it by hand.

How much RAM does a server for The Lost Era Modpack need?

We couldn't count The Lost Era Modpack's mods reliably (it downloads most of them on first start), so we can't estimate its RAM by player count. Start on 8 GB (our Premium plan), watch memory in your panel for a week, and move up if it sits above 85% at peak. Each player exploring on their own adds more.

Set Java's heap (-Xmx) 10–15% under the RAM you have, about -Xmx7000M on 8 GB. Forge 1.7.10 takes it in the java command (-Xmx), usually in the start script. RAM guide.

Different versions of The Lost Era Modpack on the server and a client show up as Mismatched mod channel list or mod rejections. Why friends can't join, timeouts included.

Lag and performance on The Lost Era Modpack

Can't keep up! Is the server overloaded? means ticks take longer than 50 ms; more RAM won't fix that once The Lost Era Modpack has enough (tick lag guide). For The Lost Era Modpack:

Distances: view-distance=8 in server.properties.
Pre-generate: with a pregeneration mod built for 1.7.10, before people explore.

Wrong Java version. Forge for 1.7.10 won't start on anything newer than Java 8, and stops with ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader. Java version fix.

After adding or updating a mod. Mods you add to The Lost Era Modpack by hand usually crash it with a missing dependency: cpw.mods.fml.common.MissingModsException names the mod.
Ticking entity or block entity. The crash report names it and gives its coordinates. Ticking entity fix.
