Since this is the longest thread with this issue, and all over the place even on reddit, there's at least 20 of us if not more, that have this issue dating back to July. It's definitely not an IPv6 issue. I have rolled back from 6.12.4 because it persists there, and also in 6.12.3. I'd like to solve this, but it's pretty out of hand. It is now almost November, so this is a really big problem. Does anyone have an update on this? I lose SSH and access to the ui., as well as unresponsive or slow CLI on local. Which then makes restarting nginx impossible. That doesn't explain SSH going out too. Maybe we should see what plugins we all have in common?
