[Discuss] Problem accessing blu.org

Wed May 20 08:41:08 EDT 2020

Here is another question for you:  what is your local network
configuration?  Are you using Comcast's modem/router directly or do you
have your own router behind their modem?  If the latter, what happens if
you try to "remove" your own router?  Does that change anything?

Another avenue to look at is whether you might be filling up the modem's
NAT table?  A very unlikely scenario, but it's certainly one I've hit (on
AT&T).

IF you can display the problem with only comcast equipment I'd phone into
their tech support.
