Connection loss leads to breakage of the plugin

[Folas1337]

What is happening?

If wherever the plugin is running loses connection to the redis server, it'll leave the plugin in a state where it's unusable.

What did you expect to happen?

I would like the plugin to attempt reconnecting if the connection ever breaks so it can recover into a healthy state after the lost connection is re-established.

Log

There are a couple lines reading like this:
[06:12:57] [lettuce-nioEventLoop-4-3/WARN] [de.themoep.connectorplugin.lib.lettuce.core.protocol.ConnectionWatchdog]: Cannot reconnect to [... redacted .../<unresolved>:6379]: ... redacted ...

What other programs/plugins are you running?

Lots but they should have very little to do with this bug/request

Additional context

No response

Oh and I had the same issue with https://github.com/Hexaoxide/Carbon and @Draycia already responded, saying the solution might be to use jedispool and even though I do not know what that even is, you can potentially look at https://github.com/ProxioDev/ValioBungee which seems to do just that :)

I never had issues with that myself (I use redis too) but I will do some testing to see if the automatic reconnect is actually not working correctly.

But just fyi: This plugin uses lettuce to handle connecting to redis, not jedis so a solution which was used for plugins that use jedis wouldn't work. ;)

[Folas1337]

Oh yeah, maybe one specific thing to reproduce my scenario:

• I have ConnectorPlugin on a backend server as well as on a velocity proxy
• The backend server did not lose connection to the Redis server but the velocity proxy did

I hope that helps track down the issue more easily :)

Any update on this problem? :)

Haven't found the time yet, sorry. Any new info would be included here.
