[quote=“Patrick, post:2, topic:1569”]What virtualizer / platform?
Please post the full output of whonixcheck.[/quote]
Sorry Patrick… the full output was exactly identical to the text posted by new2this in the other thread. I was just paraphrasing with what I typed. I am not at my Whonix machine right now, and am not sure how to copy and paste the output from the Whonixcheck popup dialog. But was this:
NFO: Whonix is produced independently of, with no guarantee from, The Tor Project. Whonix is experimental software. Do not rely on it for strong anonymity. https://www.whonix.org

(If you disabled Tor’s TransPort, please disable this check, see whonixcheck /etc/whonix.d/30_whonixcheck_default configuration file.)

I am using KVM under Linux Mint. The problem did seem to go away the last time I restarted last night, so perhaps it was just transient as you say, and self-resolved after the Tor network corrected the issue.
