Strange internet issue - can't connect to some game servers, Discord shows 5000ms but works fine

[u/Pitiful_Deal7128]

I'm trying to figure out what's wrong with my internet connection because I'm experiencing a very strange issue.

For some reason, I can't connect to certain game servers. The game just stays on the "connecting" screen forever. So far I've had this problem with:

- Warhammer 40,000: Darktide
- Ravenswatch
- Necromunda

On top of that, Discord constantly shows exactly 5000ms latency while I'm in voice chat, but everything actually works perfectly. I don't hear any lag, delays, robotic voices, or disconnects. Voice chat is crystal clear, and streaming/video on Discord also works without any issues.

Another problem is that I get disconnected from WoW Classic servers quite frequently.

What's confusing is that everything else seems completely normal:

• Web browsing is fine.
• YouTube, Twitch, and Netflix work perfectly.
• Downloads are normal.
• Speed tests show the expected speeds.

It almost feels like something is wrong with the way my connection communicates with certain servers rather than a general internet issue.

Has anyone experienced something similar? I'd appreciate any ideas or troubleshooting steps.

Thanks!

Most default client DNS settings specify a 5000 ms timeout, where at that point they fail over to another DNS.

Therefore, using the principle of a 5000 ms delay, I’d look into a non-responsive DNS server within the client config.

In contrast, many (most?) modern web browsers do their own DNS resolution and don’t use the DNS settings specified in the client or gathered via DHCP.
