Proxy checker in ob2

very confused about the built proxy checker in ob2
When using it to check proxies for the same web of the config, not working proxies can work through the web yet.
However, using the same proxy pool to check the config, lots of them are working now.
I do not know why。
Anybody has this kind of troubles.

Most likely the maximum timeout you configured when checking proxies is lower then the maximum timeout of requests in your config, so slower proxies are considered working when running a MultiRunJob but not a ProxyCheckJob.

Thanks much, my bro @Ruri
