When I try to log into the forms central site I get a webpage message saying the website is unavailable. I have the option to reload which doesn't help and a details button stating:
Google Chrome could not load the webpage because formscentral.acrobat.com took too long to respond. The website may be down, or you may be experiencing issues with your Internet connection.
Check any cables and reboot any routers, modems, or other network devices you may be using.
If it is already listed as a program allowed to access the network, try removing it from the list and adding it again.
Check your proxy settings or contact your network administrator to make sure the proxy server is working. If you don't believe you should be using a proxy server: Go to the Chrome menu > Settings > Show advanced settings... > Change proxy settings... > LAN Settings and deselect "Use a proxy server for your LAN".
I have checked my internet connection which is fine. One of my co-workers was getting the same message but was finally able to log into the website but found it very slow.
I just checked on the server and everything seems to working properly here. Can I suggest you try a different browser as a test. I suspect if may be a Chrome/Flash issue.
