Why TeamViewer is so unreliable?

MonsterMMORPG

It has been many months now that I have this particular error

The connection freeze. Then my only option is closing connection and reconnecting

However it always fails after that. So that I can't access my remote computer until the TeamViewer on the remote computer is restarted manually

Why this bug persists for many months now maybe over a year?

Currently I am trying to access my own remote computer and it fails and I can't go physically and restart it atm. So this is extremely big inconvenience and unreliability

Here the error I am having. There is no internet connection problem. This problem disappears magically as soon as TeamViewer on remote computer is restarted.

connection not established

a connection could not be established
