Hello

I have played a little with LN included in btcpayserver. I have opened the channel with coingate, transferred some sats. Channel was opened (transaction confirmed etc.), but now it is closed and I cannot reconnect to peer.
Code:
3.124.63.44:9735: Exchanging Init Messages: Peer Closed Connection.
What should I do?

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.
Advertised sites are not endorsed by the Bitcoin Forum. They may be unsafe, untrustworthy, or illegal in your jurisdiction.

How long has it been down? They may be having issues. The last update it made to 1ml.com was 14 hours ago from when I am posting this:

https://1ml.com/node/0242a4ae0c5bef18048fbecf995094b74bfb0f7391418d71ed394784373f41e4f3

As a rule, a node with that many channels and transactions and 37+BTC tends to update a bit more. Not a definitive answer but a possibility.

I can connect to is as a peer but it will not let me open a channel. So, I am *thinking* it's them but it could also just be us.

It is like that for at least 12h. OK, not a big deal, I will try tomorrow.
Hard to say, is it better to trust a giants or smaller peers...

I have some channels open to other places that only have a few other channels and not a lot of funding, and some other places that I have channels open to 100s of channels to other places and a lot of BTC.

Having a lot of different ones open allows for a bunch of possible different routes. The larger places tend to have higher fees where the smaller ones tend to be less costly.

Still talking only a small amount of BTC in fees in the end, but still....

No need to worry and no need for 'trust' either (since you mentioned this word earlier).
Worst-case, you unilaterally close the channel. I do believe channel partners are even punished a little, for disappearing and requiring such a force close.

There can be penalties, depending on the settings you used when opening the channel. The issue can be that if you are not paying attention or if you or the other side have changed some things you may have to wait a while for the force close to happen. Not a big deal unless you need the funds now, but if you do you should probably not have them in an open channel anyway. I use LN a lot but still full understand, things can still go wonky.

As an example, think of all the people in Cuba, Florida, and anyplace else that was just fucked up by Hurricane Ian. If you were running a node at home, or in your business, you stand a good chance of being offline for weeks now. If I had a channel open to someone there, and there is really no way for me to know where you actually are, I could wait a week before deciding to do a force close, and then be waiting 'x' number of blocks / time for that to actually occur. Through no fault of mine.

That's all true, I just want to correct any worries or doubts about 'security' and 'trust'. There are lock times, which can be rather long, but those don't mean you won't get your money. There is absolutely no need to trust a channel partner in terms of them stealing your balance or permanently locking your funds by disappearing.
But it's true that it would be annoying if channel partners were to do this all the time and you'd be constantly stuck with channel closing transactions waiting to be spendable.

As an example, think of all the people in Cuba, Florida, and anyplace else that was just fucked up by Hurricane Ian. If you were running a node at home, or in your business, you stand a good chance of being offline for weeks now. If I had a channel open to someone there, and there is really no way for me to know where you actually are, I could wait a week before deciding to do a force close, and then be waiting 'x' number of blocks / time for that to actually occur. Through no fault of mine.
That's true; it's how the Lightning Network is designed. So that you're always guaranteed to get your funds back out, even though it may take a while.
The only risk in such a scenario is that if you knew for certain that the channel partner is going to be offline for a while and that they have no way of restoring a node backup on an AWS instance or don't have a watchtower set up, you could attempt cheating on them.

But for you, there is no risk (referring back to the terms 'security' and 'trust') here other than losing 'time' / opportunity cost to do something else with those funds during that time.
