My Mac cannot connect to sonsofsamhorn.net

[HriniakPosterChild]

The Windows machines in my house can load sonsofsamhorn.net. My iOS devices can load sonosofsamhorn.net. But as of this afternoon, my Mac Book Pro (Yosemite 10.10.4) is having all sorts of problems loading sonosofsamhorn.net.
 
Safari is glacially slow at loading any page on the site.
 
Chrome shows an error page after a long wait: "No data received / ERR_EMPTY_RESPONSE / Unable to load the webpage because the server sent no data."
 
From Terminal, curl http://sonsofsamhorn.net prints "curl: (52) Empty reply from server"
 
I have rebooted the Mac and power cycled my cable modem and AirPort Time Capsule, but it hasn't fixed the problem.
 

 
What should I try next?

I got the error messages on my PC for  a few hours today. Eventually started working. Didn't do any fancy fix. Logged out I could load it, logged in got the message.

have you tried to clear your cache?

 

[HriniakPosterChild]

Which cache? Chrome and Safari don't use a common cache, and curl from bash doesn't use a cache at all.
 
Firefox is no better, BTW:

The connection was reset
 
The connection to the server was reset while the page was loading.

•     The site could be temporarily unavailable or too busy. Try again in a few moments.
•     If you are unable to load any pages, check your computer's network connection.
•     If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

It's looks like it's timing out while connecting to an IP, after DNS resolution. So clearing the DNS cache may help. But if Safari works at all it's probably not that. You could try looking up the sosh IP on a known good machine, accessing the site by IP from that machine, then accessing it by IP from the MBP. Unlikely though.

Strange problem, doesn't sound like DNS, doesn't sound like Chrome/quic weirdness, doesn't sound like the router. Try the MBP on another network?

 

[HriniakPosterChild]

I tried MBP on my iPad Personal Hotspot, and SoSH loaded instantly. So if I take the MBP to an Apple Store and ask for help fixing my connectivity problem, I will not be able to repro the problem.
 
Signs point to some cause inside the AirPort Time Capsule. I have learned that Apple does not offer chat support for this product in the middle of the night, and the MBP chat support I connected to is unable to help.
 
I'll update this topic after I chat with the right people tomorrow.

I use a MacBook Pro and it was giving me some problems today but I think everyone had the same issues.  Had a couple of "server connection" problems lately but seems that it has worked itself out.

I rebooted earlier today. Your router is probably doing something weird, it's the only variable in the mix of its working elsewhere

 

[AlNipper49]

Earlier yesterday, duh

After 2+ hours on the phone, it is recommended that I wipe my Mac HD and reinstall the OS.

There is a phrase that ends with, "red hot poker."

Do you have Avast or any other anti-virus installed on your Mac?
I'd typically advise removing all anti-virus from Macs; they are secure enough due to good user/system permissions.  Others might disagree with me.
Also try removing/disabling any software that makes modifications to networking system: VPNs (third party and corporate, Cisco, OpenVPN etc.), Parallels/VMWare/VirtualBox, Little Snitch.

It's actually not TOO hard to do that if you use a Time Machine backup, but I would still only do it as a last resort.  Beyond removing any third party software, it's unlikely to help.   I'd try a factory reset on your wireless router / cable modem before I tried anything else.

 

[HriniakPosterChild]

I do have Avast, but I do no have any VPN's or VM hosts.
 
If I reboot with Command-R, I can load sonsofsamhorn.net by typing the URL into the "Help" option's URL bar. So I am told that a reset of the AirPort Time Capsule is unlikely to solve the problem. Interestingly enough, creating a second User account on the Mac and connecting to SoSH from there does not work. So it's more likely to be a system thing instead of a user account thing.

Edit: I will try removing Avast before I wipe the drive.
Edit2: Yep, I can connect after removing Avast.
