Can't connect to servers in 1.19; Can in earlier versions.

When using Minecraft Java edition, 1.19 seems to function normally for the first few days. Then, afterward, it will no longer connect to servers, simply saying "Timed out". The logos, connection strength meters and messages from the servers will still appear in the server list. This affects all computers in my household, despite switching routers, reconfiguring DNS, reinstalling Minecraft, and using different launchers. Does not affect play over mobile hotspots.
