Hi all.
After upgrade to 2022.5 version my setup ran into problem ,that looks like hassos cannot reach internet.
First symptom was that HACS very often had:
Background tasks pending
Some repositories might not show until this is completed
Ignored that, after restart this warning dissapeared. Then when I tried to update addons from HACS they did not update any more, and in logs were this:
Download failed - Cannot connect to host objects.githubusercontent.com:443 ssl:default [Try again]
Request exception for 'https://api.github.com/rate_limit' with - Cannot connect to host api.github.com:443 ssl:default [Try again]

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):

The above exception was the direct cause of the following exception:
Traceback (most recent call last):

But on HA core startup, when HACS has started, it successfully scans for updates, and offer them for install.
Also realized my command line sensors stopped working, like:
- platform: rest
resource: http://icanhazip.com
name: external_ip
value_template: '{{ value }}'
scan_interval: 3600
gives me error:
Error fetching data: http://icanhazip.com failed with [Errno -3] Try again
Also find out that System Health shows me unreachable endpoints:
Home Assistant Community Store

ha dns info gives me:

Intersting part that, when I ping gihub.com via hassio terminal it gives me bad address, when I ping githubs IP it pings, and afterwards I can ping host github.com
ping github.com -c 5
ping: bad address 'github.com'
ping:140.82.121.4 -c -5
PING 140.82.121.4 (140.82.121.4): 56 data bytes

Also tried to set IP static not dhcp( with reservation), Rebooted/upgraded Mikrotik router, restarted Hassos Host (now v7.6), had instlalled adblock guard addon (but it was disabled all the time) removed it.
I have run out of Ideas it it all is really weird. I have not set up any ACLs in my netowork, and with this network setup my HA Core has ran for 4 years without any problems till now.
Installed test HA Core instance on Hyper V, upgraded it to latest HA Core and on this machine there is no such a issue.
PLease help me to resolve this strange issue, as it is driving me nuts 
about page:
Home Assistant Core 2022.5.5
Home Assistant Supervisor 2022.05.3
Home Assistant OS 7.6
Kernel version 5.10.103-v8
Agent version 1.2.1
Time is correct on Homeasistant Core
It definetly looks like DNS issue
