Pihole not able to update

[coderpop]

Please follow the below template, it will help us to help you!

Expected Behaviour:

pihole should update from raspiban and pihole servers, it should allow other devices to get ip lookups.

Actual Behaviour:

After a long run without any issues, suddenly things seem to have gone wrong......

Pihole cannot connect to raspbian or pihole servers. (ping servers from my laptop works OK)
No other devices can update when using pihole as dns server.
Gravity update fails.
pihole-d freezes at *** [ DIAGNOSING ]: Dashboard and block page ----- So no debug log available.

 ip -4 route
default via 192.168.1.254 dev eth0 src 192.168.1.31 metric 202
192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.31 metric 202

So the above looks OK to me....I am confused as to what has happened....This tells me to contact pihole support...

By changing address in hosts file from 127.0.0.1 to 1.1.1.1 I was able to update successfully.....

Now I can also generate a debug token.....

Things seem to be working OK now, but if someone would be so kind as to have a quick look over the log, then that would be great.

The first few are operating system level errors, and the last one is a warning due to a misconfigured config.
