This just started to flare up ~2 weeks ago on our v1.17.1 server (running on Mac OS X 10.15.7, Mac mini[late 2012], 16GB RAM, upgraded to Samsung SSD[1TB and 2TB], and exclusively just runs Minecraft server). Up until then, it had been running flawlessly, with 5 full-time players online concurrenlty and seperately throughout any given 24-hour period. We also have another Minecraft server that is running on even more robust host system (e.g., newer iMac with 32GB RAM and SSD's) that started to have the issue at the exact same time. The WAN connection is strong (1Gbps download and 50 Mbps upload) and the 2.5Gbps LAN network uses Ubiquiti UniFi router, switches, etc. that are less than 2 years old. The clients that are connecting over the internet all have good internet speeds, with average ranges from ~50Mbps - 250Mbps download and ~10Mbps - 30Mbps upload.
Seeing that many here posting are having the same issues, even when using cloud-based hosting solutions for their severes, reaffirms my suspicion that it's not an issue with either the server host or client networks but is instead a bug that is either on the Java server or Java client side. This has made playing impossible unless one is on the LAN of the sever host, and most of our players are several states away from us while at college. This is extremely disappointing and frustrating, to say the least. 😞
