The wechat page has no content, why does the package display session ticket empty?

recently, when Wechat opened the page, there would be a blank page. It was OK to open it for the first time, but it could not be opened several times later. What I found for the first time was that I returned to No content, to check the information and did not see why. The second time I grabbed the bag and found that there was session id, but session ticket was empty, who did not understand the introduction of SSL,TLS. I hope God can give me a way of thinking. Is it the wrong direction for me to solve the problem?
