Some mobile phones visit https to display a blank page.

Here's the thing. Omit 1000 words here!

All of a sudden, the customer service told me, why can't we log in to the consumer platform that enjoys all the wins? And it always shows a blank page. Hey, programmer, what have you done? Well, then I looked confused.

Then I hurriedly picked up my phone and clicked on the winning consumer platform, and then everything was normal and normal on our side. Normal, can no longer be normal!

Then I asked the consumer's phone number, consulted the situation with perturbed heart, and then picked up a real machine test platform for testing, and sure enough, it could not be opened. It won't open?

Then I started looking for problems, looking at the server log, looking at the code, printing the code. This is the first time I've seen it. Is it because Huanxin is not compatible with this god-like oppor7, or maybe you dug a hole and found that you didn't access our server? At this time still do not realize the problem, continue to check the code. Until at some point, I suddenly realized that not accessing the server was definitely not a problem with the code (previously suspected, but not sure), and then wondered if it had been intercepted by the carrier. Use wifi and traffic are not good, ruled out! Finally, it is found that it is the problem of https incompatibility! It turns out that Tencent's https is not compatible with the lower version of the Android system, if forced access will show a blank page! After that, I replaced the https certificate of Qiniuyun and so on, which is normal!

Finally, Tencent's free https certificate configuration is not compatible with the lower version of Android (4.4.4), so your partner finds that some phones on your site show blank pages, so you should replace them in time. I don't know when Tencent will be able to solve this bugboat problem!

I am far from success!!!
