Missed a block but not an orphan. Can you figure out what happened?

So just missed a block for no apparent reason.
Both relays are running fine, and BP has been up for 2 days, processing transactions and we minted a block just a few hours prior.
{
“no”: 3,
“slot”: 39210028,
“slotInEpoch”: 157228,
“at”: “2021-09-04T13:25:19-04:00”
},

A search on Cardano Explorer doesn’t tell me who minted this block over us.
This is our first missed block that wasn’t an ‘orphan’ and I’m trying to make sure I know what’s happened to prevent any possible future problems.

I missed a block also

Could we be missing blocks because not everyone is on 1.29?

I don’t think so, Anti.biz. My cardano-node log file from the missed block is below.
Looks like there was a fork and someone else’s tip was accepted over mine.
Could someone mind taking a look at this log and telling me that’s all this was?
Usually when this happens, Pooltool.io will log an “orphaned” block, but for some reason it’s not showing up. Just making sure my this is just that random bad luck that will cause you to lose a slot battle about 1 in 20 blocks…
Thanks!

I’ve had the same problem just yesterday. The first time it has happened. I have a similar log as you. Has anyone got any thoughts? It doesn’t show up as an orphaned block on pooltool, it’s as though the block doesn’t exist…

Hi guys, I just missed a block a few hours ago as well. I tried using Cardano explorer to see who minted the block but I can’t even find the slot or any info regarding the slot. My logs also appear to stop a few thousand slots before the missed slot so I cant find any info regarding why I missed the slot.

In my situation, I believe it was just a slot battle I lost. There is a chance it didn’t appear in pooltool because I wasn’t sending my tip at that moment.
But I have had the same experience since then one other time when I know I was sending, yet pooltool didn’t show it. Still not clear on what would cause that.
