all servers unreachable

[zeroone1zero 0]

v2.20, ipv4, Tap adapter (tunnel adapter would never install)
No recent OS updates.  No active AV.

The vpn worked flawlessly for a long, long time.  5-Star server scores
were bountiful. Then a couple of weeks ago I noticed it bogging down trying to connect to a server and that the server scores were 2-Star at best.

For a week or so there were 2 servers that I could connec to successfully.
Then they too were unreachable.

I have checked and rechecked settings.  Disabled, uninstalled and re-
installed v2.20.  Installed v2.24 and the behaviour was unchanged.  I then
went so far as to restore a 1 year old Macrium image -- to no avail.

Hopefully some kind soul can take a look at the attached log file and help
me sort this out.

TIA
