Sounds like you were out of resources. That is the goal of a DoS attack, but you'd need connection logs to detect if that was the case.

DDoS attacks are very tricky to defend. (Source: I work in DDoS defence). There's two sections to defense, detection and mitigation.

Detection is very easy, just look at packets. A very common DDoS attack uses UDP services to amplify your request to a bigger response, but then spoof your src ip to the target. So large amounts of traffic is likely an attack, out of band udp traffic is likely an attack. And large amount of inband traffic could be an attack.

Mitigation is trickier. You need something that can handle a massive amount of packet inspection and black holing. That's done serious hardware. A script kiddie can buy a 20Gbe/1mpps attack with their moms credit card very easily.

Your defence options are a little limited. If your cloud provider has WAF, use it. You may be able to get rules that block common botnets. Cloudflare is another decent option, they'll man in the middle your services, and run detection and mitigation on all traffic. They also have a decent WAF.

Best of luck!

Most people just use a browser these days, and they behave the same in every OS.

Steam has proton to run non native games on Linux, and works well enough for most things.

Try a few live images before making the switch.

You don't require docker to self host. You have a lot to learn, so trimming down the amount of things your doing is the right idea. Ignore it for now.

You don't have to buy a domain, you can use your IP directly, or use a free dynamic dns service.

Mastadon may be too complicated for a first host for a beginner. I would recommend trying something simpler first, but it's your hobby so do it how you want to.

Looks like you've edited /etc/default/grub with a kernel flag that may not be supported.

Try removing i915.enable_psr=0 from that file and trying again.

EDIT: Typos. I'm on mobile

Your host sets it's own DNS servers, if the router isn't on the list, they don't get pinged. Now they could try to man in the middle you, so you could try DNS over TLS, but it's probably not your issue.

You're DNS server settings likely never took hold. Like if you use a DHCP client, then override your DNS settings, that won't take effect until you request a new DHCP connection.

Some Linux distros will have local DNS servers that you always point to which are a pain to update as well. Not sure about Windows and MAC.

good luck man!

Try changing your DNS server in that case!

I would migrate the domain. Don't bother with flakey services. Cloudflare free tier can do some amazing things.

In the meantime set it in your host file to the correct IP to get by.

I migrated from Plex to jellyfin.

I tried it out when I couldn't get HEVC files to steam on Plex, and i liked it!

It doesn't have the full ecosystem around it that Plex does, but that's fine by me.

Buddy's writing is a bit pretentious, I had to stop reading a few paragraphs in.

It's too bad, too. I likely agree with him.

I have the exact opposite problem. Windows is an unstable bloated mess I don't understand. Linux just works.

I use a Mac for work, and it's alright, but it's got it's janky parts (key bindings, and being forced to drag and drop things for instance)
