Yeelight Forum Bug

Hi, does anyone notice that there is bug for Yeelight Forum.
If you click on an external link, it will show “This page is not working”.
Then, if you click back to the previous page, it will still not working.
Can only go back to the previous page after few minutes.
Is it only me?
I have tested with 3 computers, all have same response.

Yes, sometimes it happens to me.

I check it in your way, but it seems not appear again.
I guess that it happened because of the forum use pjax , sometimes it can’t handle the right http status.
And forum base on the “discourse” system( Ruby ), i know few Ruby ,so , ignore it if it not often effect your experience.
