Tor connecting to random guard node IP addresses as of today despite EntryNodes set

I have

StrictNodes 1
EntryNodes [two guard nodes]

set, and this has only ever connected to those two IP addresses, now today it connects to another random guard node IP address at every start, and I see it send 20-30 packets.

What is up with this? Someone can explain?

Edit:

ClientBootstrapConsensusFallbackDownloadInitialDelay 6

Why does this fix it? It’s 0 seconds by default, despite a similar option being a 6 second delay by default.

Nothing on my system changed in weeks, so this must be network side. Also did you notice 9 out of the 10 directory authorities have double-digit advertised bandwidth?

I have also noticed a change in which when I go to Reddit Onion site I see a strange certificate error. Unexplained Certificate error

I am interested in trying guard node selection. Did you just enter the IP separated by a comma ?
