What version of Client Control plugin are you using? Do you have Login Anonymously enabled or disabled in Client Management? You can switch it to Disabled, Save the settings and see if that changes anything.
Client Control plugin I had in version 2.1.2, which I have updated now to version 2.1.3, but the problem persists.
In Client mamagement have Login Anomymously disabled.
I can't figure out what is happening on your end. If you have AnonymousLogin on Disabled in Client Management, then it shouldn't be set to true in spark.properties file. Every time Spark logs in it checks Client Management settings and should be setting it to false. Same with other settings. Default for these settings is true. So maybe your client for some reason can't access the server and read these settings. But that's not very realistic. Anyway, this is puzzling. You can also try checking the logs C:\Users\username\AppData\Roaming\Spark\logs
thank you for answer. Plugin Client Control will be OK, becose I disabled the plugin, but the problem persisted. I tried to look for errors in the log and found a connectivity problem. See below. I will try to find a problem on the server or on the network.

That timeout error is often seen in the logs and is probably unrelated.
