I'm not getting the 502 Bad Gateway.
But I am getting this running Chrome when trying to view the forum.
Right now I'm using FireFox to access AZB.
Using Chrome I can access the AZB Home page, if I click on Forums this is the message that is displayed:
This site can’t be reached
The webpage at
https://forums.azbilliards.com/ might be temporarily down or it may have moved permanently to a new web address.
ERR_SPDY_INADEQUATE_TRANSPORT_SECURITY
To investigate this, in the address bar using Chrome I typed in:
chrome://net-internals/#dns
This brings up a cache list of certificates of sites visited.
Scrolling down the list I have noticed that AZB has some expired certificates and this is why Chrome will not let me access the forums.
Just trying to help out Mike.
