I have 5 folding rigs which run 24/7, mostly unsupervised.
While checking my stats today, I noticed a problem (big drop)

Then, upon trying to check from https://v8-4.foldingathome.org/machines only the 1 machine running MacOS (the other 4 are running Ubuntu) was reachable / connected

Once I was able to check locally, they all seem to be folding fine (judging by power draw from the UPSs), but not even locally I can login to web control, it gets stuck (indefinitely) logging in

All running v8.4 (macOS updated last week [8.4.9], 2 ubuntu boxes updated today [8.4.9], the other 2 a few weeks ago [either 8.4.8 or 8.4.9].
Edit: I am located in Indonesia. Perhaps some geo-restrictions again? Last year there were a few months when I could only get WU's assigned only when using a VPN.
Has anything changed?
Anyone experienced something similar?
Ideas?
Cheers,
enroscado
