Hello @lucko !) LP works good for 1.10.2-2281-5.2.0-BETA-2567, but version 1.10.2-2281-5.2.0-BETA-2569 and 2571 have next errors:
All plugins for work in MySQL not connecting and work. I is error in LP, or SpongeForge?)
LP version: LuckPerms-Sponge-3.3.3

It's not a crash, rather, the MySQL driver installed on your server isn't working for some reason.

Can you try updating to a newer SF version?

SF last in this page: https://www.spongepowered.org/downloads/spongeforge/stable/1.10.2
Thanks for the explanation, without knowledge of English it can sometimes be difficult to understand the errors and their consequences) I'll write issues in SF)

I doubt it's an SF issue.

More likely that you've installed a mod/plugin which is packaging an older/newer (either way conflicting) version of the driver.

Version 1.10.2-2281-5.2.0-BETA-2567 and previous such errors do not cause) Only version 1.10.2-2281-5.2.0-BETA-2569, 1.10.2-2281-5.2.0-BETA-2571

Ok, and if you downgrade again, it works?

Yes, server works, and there are no errors this 1.10.2-2281-5.2.0-BETA-2567 or previous version.
SpongePowered/SpongeForge#1735
Last version 3.3.8 have this error too

Have you actually tried downgrading to the SF version which works?
I don't see how if that works, it could possibly be a LP issue.

blood is also mistaken, the error has nothing to do with loading groups.

[23:03:22] [Server thread/INFO] [STDERR/sponge]: [me.lucko.luckperms.common.storage.backing.sql.SQLBacking:init:197]: com.zaxxer.hikari.pool.HikariPool$PoolInitializationException: Failed to initialize pool: java.lang.NoClassDefFoundError: com/mysql/jdbc/MysqlIO

We are effected by this bug too, it has to be something in Sponge as no downgrade of LuckPerms will fix it only downgrading Sponge will help.

@lucko All we did was update our database connectors

SpongePowered/Sponge@c4d8144

Update: This was only done to bleeding so not sure.

Looks like this may be related to our new track method system. So don't bother looking into anything on your end.

Alrighty. Thanks blood.

Same issue here after updating from spongeforge-1.10.2-2281-5.2.0-BETA-2464 to spongeforge-1.10.2-2281-5.2.0-BETA-2585.

I can't completely follow the comments above. Do I need to wait for a fix in sponge or luckperms?

Sponge.

Afaik, there's already a fix out, as of 3 hours ago.

Alright, thanks.
