Client crashes when loading assets

You have a TTL on your domains of 5 minutes. That means cache is "forced" to check every 5 minutes for resolving the name to an IP.
Now there are ISPs with their own DNS which fails because of whatever reason.
Using a reliable DNS server is one solution, fixing domain and IP another. Setting a much higher TTL would also help.
Nothing you can do to prevent this, other than not using domain names and revert back to IP. The easiest fix would probably be a higher TTL, except you are planning to switch servers again soon.

Not sure that explains it, though. Again, the weirdest part is that noone ever complains about the website and the launcher seems to work. It's just the client proper that fails to resolve the names.

I never had this issue. But I have friends that had this issue. All of them were from overseas. None of them had this issue when they fixed the name and IP in host file or were using custom configured DNS.

I would not go so far and see any issue in java / the client.
Browsers are more resilient... Look at DNS prefetching.

I don't see DNS prefetching as a resiliency feature, but rather a performance optimization, but regardless of that, it still doesn't explain why the Launcher (which is also written in Java) works, while the client doesn't.

The way I see it, if I implement any type of caching mechanism, that prevents random DNS Issues, gaining performance and resilience is both a valid outcome of that.

In any case, the Launcher is started ever so often while the game sends request over a longer timespan regularly. Statistically the chance of having a hiccup is way higher in the game than on the launcher.

If I remember correctly you send yourself errors anyway, why don't you just collect the info on that one until Friday and then just change the TTL to 1h or 6h for testing purpose and see if a week later the frequency is lower.
I bet you a 90 day gold sub it will. Would love to see the raw data on that one.

That was my previous thought as well, but in this thread people are claiming that it fails consistently and that they can't even properly log in.

It doesn't happen very often, so I kind of doubt I have enough reports on it to create reliable statistics, but I'll look over the data and consider it. If I can get reliable data, it can certainly be worth trying.
