This is an issue that, while not all that bad, is quite frustrating to say the least. It's very common for me to be disconnected whilst attempting to log in. This will happen dozens of times before I successfully load into the world. This comes in compact with a similar error that occurs when I try "dimension hopping" (Which is basically me going to and from dimensions). There runs a chance that I'll be disconnected, which only furthers this obnoxious bug. That's the one the that usually occurs when "dimension hopping". and... These two occur damn near daily when logging in. Especially the one that says "Disconnected".
