As shown in the following figure.
Page content does not always show this, the general meaning is to tell you can not open the Chat window, you want to "initiate web chat."
Before you can eliminate the reason, you must set up a temporary session first, which is required.
There are two aspects to this cause:
One, your QQ software is not in the official download, is modified version, some modified version, changed some components, such as some modified version of the TIMWP components removed, so it is easy to open the chat window.
Second, encounter such a problem, it is best to send other friends to see. If a lot of people have such a situation, then is your customer service QQ in the Tencent server problem, if only a certain QQ click on this customer service QQ when this situation, then only to initiate the conversation of this QQ is the Tencent server problem.
Tencent users, more servers, their servers are sometimes to maintain, the server initiates a temporary session, and Friends Chat server is not the same. Temporary session, you must pass the Tencent server, first check this QQ allowed to not allow temporary sessions.
