have also noticed that tweaking settings so its less graphics intensive (i.e ingame settings, roblox graphics quality) can help prolong play time in certain places. have been thinking if high usage and intensity could also have something to do with the disconnecting issue. i tried it today and in a game where i had been disconnecting after 15 minutes every day i managed to reach a play time of 30 minutes did not disconnect and left on my own (this week and last week i have been timing play sessions) hope this helps.

Issue still persists to this day, it definitely depends on the ISP as I just changed internet and the problem started happening. Technically I don’t know whats the “factor” in the ISP that makes this bug happen. That would be interesting to know.

i dont know if its just me, but i feel like its really intensified this past month. other days i wouldnt give it much thought but now i am lucky to even scratch 15 minutes. except for very late at night like 2am-ish where it improves alot but at that point its just useless because its late.

I also got this recently twice in a row while playing Notoriety. One time it briefly reconnects and my frozen inputs get sent one after another, and then freezes again while still being able to fire my gun (client handled) and move around
Though I didn’t know when it froze since I only noticed it when I tried to interact with a Guard but can’t do so

Lowest time - 3 minutes (can often happen 3-4 times in a row)
Average - 15/18 minutes
Above average - 20/25 and beyond
longer games like 55 - 1 hour games usually only happen to me later at night at like 2 to 3 AM, as for why this happens I dont really know, is there an explanation to this?

It’s crazy how this issue is there since last July and it’s still not being fixed yet
As for me, it usually happen after roughly 45 minutes - 1 hour after I joined an experience, and it’s definitely not an Internet nor a computer issue since I have pretty much the optimal equipment to play roblox decently

not just last july, thats when this forum was made. this issue has been around since atleast 2021, unfortunately it didnt seem to get picked up as most of the people talking about them were in comment sections or reddit threads that ultimately went nowhere and ended up going unnoticed.

Thank you to everyone who sent logs and posted details to this thread over the holidays;
In order to iterate more quickly on this issue, I am enrolling certain users from this thread to a special Roblox version which will allow us to gather more logs and enable fixes as soon as we find them.
If you check your Roblox logs and see a line saying the channel is “ZphantomFreeze”, you will know that you are enrolled.
Thank you for your patience and for your assistance in chasing this tough bug.
EDIT:
For transparency, these are the users I have enrolled to the special binary. Please DM me any new logs you have from sessions that you experienced the issue! (typically, the log file will contain the RakNetMissingPingPong log)

I haven’t played a lot of Roblox games in a while but I’m starting to play again recently.
Feel free to add me to this beta/test as well so I can send logs in case this issue happens again.
I’ve had it a few times recently but it seems a bit more rare now so it’s trickier to catch + I cleaned logs a while ago since it was starting to take up a lot of space on my hard drive.

When did yall roll it out? I haven’t been having issues with it for a while, so I don’t know if this new version fixed it.
Mine seems to show the channel as “zsocialcoexprelease” I might be on multiple channels?
I would like to be enrolled. I have lost so much stuff in games because I keep getting silently disconnected within 20 minutes of joining, it’s not fun 
I noticed today that Roblox client allows for much longer period to sync back instead of silently disconnecting, but it’s not always the case and I don’t know how long this will last, it may or may not be related.
