Hi all
Can anybody hrlp please?

Macbook Pro Mid 2012 running El Capitan

I am getting cannot conect to server on the following:
App store
iTunes store
Neptunes lastfm sign in
Lastfm scrobbler sign in.
(tried a ping to ws.audioscrobbler.com says host down, it wasn't)

Suspect it is some sort of permission problen?

Hello,

-I assume you can connect to other Internet sites?
-Is this a new issue - did it connect previously?
-Have you changed your router hardware or any settings in System Preferences > Network recently?

[Alistair Shield]

Thx for the reply.
Internet fine, mail fine. It's just the items listed. I don'think I have changed anything and they were all working on Wednesday.

 

[Cory Cooper]

No worries.

-I assume you have restarted your Mac since the issue began?
-Are you connected via Wi-Fi or Ethernet?
-Are you using manually entered DNS server settings?

Hi
Rebooted, on wifi, using local and 8.8.8.8

 

[Cory Cooper]

Can you post a screenshot of the DNS settings window?

C

 

[Alistair Shield]

As requested. Screenshot of DNS

 

[Cory Cooper]

OK...

I would try removing DNS Servers: 192.168.1.128 and Search Domains: Local. See if that restores access. Do you have them entered for a specific reason?

[Alistair Shield]

The local thing and 192.......were just there. Mac is a refurb, but had been wiped. Took them out, but no joy.

 

[Cory Cooper]

OK...

Next thing to try: logout of the App Store, restart the Mac, log back in.

C

 

[Alistair Shield]

Done

 

[Alistair Shield]

Done

Still nothing

 

[Cory Cooper]

OK...

-Are the date & time correct on your Mac?
-Do you have System Preferences... > Security & Privacy > Firewall enabled?
-In System Preferences... > Network > Wi-Fi > Advanced... > Proxies is anything checked/enabled, and does it show *.local, 169.254/16 in the box below Bypass proxy settings for these Hosts & Domains:?
-Are you using DHCP in the TCP/IP section of the Network preference pane?
-You could try removing the 8.8.8.8 and 8.8.4.4, turn off Wi-Fi, turn it back on. It should autofill from your router.

[Alistair Shield]

Date/time ok
firewall enabled
169.... is there no boxes ticked
dhcp Yes
wifi repopulated with 192........ as above

 

[Cory Cooper]

Try turning off the Firewall

C

 

[Alistair Shield]

No joy

 

[Cory Cooper]

Wow...this is puzzling.

-El Capitan 10.11.6, correct?
-Do you have an iOS device that is connected to the same Wi-FI? If so, can they reach those services?
-How about trying a modem/router power cycle...

C

 

[Alistair Shield]

El Capitan 10.11.6, no other Apple device. I rebooted the rooter already

 

[Cory Cooper]

OK, we'll go a little more nerdy...

Is this Mac your only connection to Mac Help? If so, beware that this will reset all settings for Network and you may have to reconfigure a bit, including authenticating to your Wi-Fi network with user and password.

Delete this file and restart you Mac immediately:
/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

Nope
