today i wanted to look into getting backblaze working on my account, oogged into the TOS front end, the HELP screen opened but alerted, no internet connection, i tried to open backblaze, and i only get a blank screen

i ssh in, try to resolve google.com ,

Code: Select all

nslookup: can't resolve 'google.com'
[root@MEDIA user]# nslookup google.com
Server:    127.0.0.1
Address 1: 127.0.0.1 MEDIA
nslookup: can't resolve 'google.com'
cat /etc/resolv.conf
Empty File.

i set network interface from DHCP to manual. .. still no resolution, i set interface back to DHCP still no resoltion

manually edited resolv.conf and add in 1.1.1.1 and 1.0.0.1

Code: Select all

[root@MEDIA user]# nslookup google.com
Server:    1.1.1.1
Address 1: 1.1.1.1 one.one.one.one

Name:      google.com
Address 1: 172.217.20.142 google.com
Address 2: 2a00:1450:4009:801::200e google.com
any ideas why i lost resolution ? it was working last week ?

This should be a problem with your network.
You can first try to obtain the IP manually.
The first three digits of IP and gateway need to be the same.
