Information about the issue/bug

It says the player is not connected, in bungeecord. Also autocompleting is only listing the players in the server not in the velocity network. This only happens in this server, not in the others. Is incosistent across the servers

Thanks, I'm out of office for the week, I'll look into this with highest priority when I come back. How is that one server different from the other servers? Does it have bungee.yml file configured and enabled?

[zestian56]

@kangarko Updating the issue: This is happening intermitently on my others servers. It happens with high player count, like 300+. Some servers just stops working the msg. but when the server is with low population it works.

I think a possible vector to look into is how RedisBungee can be so finicky, especially when the system time of each proxy server is not synced. It tends to desync player data fairly often, causing the message [redisbungee]: De-synced playerS set detected correcting.... to occur. I'm not sure what all VelocityControl can even do to combat this, when this very much seems to be a redis/RedisBungee issue. Finally have a useful error message:

Fixed this issue by using the Redis pterodactyl egg instead of the manual install. But new issues cropped up (separate Github issue)

[zestian56]

For my issue im not using redis btw

I'm rewriting the chat sync in the upcoming ChatControl 11 to use more compression. It should no longer happen in the next version. No ETA, but should be out by the end of next week.
