One of my players having issues with disconnecting/connecting

Hi all! Description (and how to reproduce symptoms): I'm running a 6-player game.&nbsp; Everyone is using Roll20 without issues, except for one of my players (Chris).&nbsp; Sometimes the game works fine, but 90% of the time Chris sees the following symptoms: - If Chris sends a text message (or rolls the dice) in chat, everyone else can see it immediately (including Chris himself) - But if DM or another player types something in chat, it can take 5-30 seconds for it to appear in Chris' chat window &nbsp; -- When DM or another player send chat message (within 1-5 seconds), Chris' name (video/avatar) disappears from lower left corner of Roll20 &nbsp; -- After 5-30 seconds, Chris' name (video/avatar) re-appears (lower left corner), and Chris immediately sees the chat message In addition to chat messages, other things cause the same symptoms: - If the DM moves a token on the map - If the DM moves the party to another map - Etc. (i.e., pretty much any change made by someone other than Chris) Other things of note: - Chris uses Windows Security (firewall), and the problem persists even if his firewall is disabled. - This problem started about 1 month ago.&nbsp; Before that, he had no issues. - He tried using both Chrome and Firebox, same issue. - Chris is using a desktop PC - Chris has completed Steps #1-4 of the following checklist: &nbsp; --&nbsp; <a href="https://wiki.roll20.net/Solving_Technical_Issues" rel="nofollow">https://wiki.roll20.net/Solving_Technical_Issues</a> Computer Settings: - Web Browser: Google Chrome (Firefox also has same issue) - Browser Version:&nbsp;Version 86.0.4240.183 (Official Build) (64-bit) - Operating System: Windows 10 (64-bit) - Javascript Enabled: Yes - Antivirus Software: Windows Security -&nbsp; List of any browser add-ons or extensions enabled: &nbsp; --&nbsp; Google Docs Offline &nbsp; -- Chrome Apps (Docs, Sheets, Slides) *************** Console Log: Some messages have been moved to the Issues panel.

This has something to do with connectivity and as always with connectivity issues there can be many reasons: - it can be something in his house: As it started after a certain date: windows update? browser update? broken cable? new neighbour that conflict with your wifi. There are so many possibilities. - it can be something with his ISP. Maybe the ISP has overbooked too much and is out of bandwidth. Maybe there is a switch overloaded or broken. Maybe some builder hit a cable somewhere, enough to cause anger and not enough to cause a full outage. There are so many possibilities. - it can be something with the connectivity between his ISP and the rest of internet. There are so many possibilities. Things to try/consider: - how is Chris PC connected to internet. Wifi? Ethernet? Mobile? - which ISP is Chris using? is that a different one than the other players.

Thanks Martijn!&nbsp; Just to clarify, Chris is only having issues with Roll20.&nbsp; And he's having issues with 2x different D&amp;D campaigns on Roll20 (each with their own DM and players).&nbsp; So I think it's something within Roll20, not his ISP, browser, Windows, etc.&nbsp; Chris' PC (desktop) is connected via ethernet cable to his router/modem.

Of any action with Roll20 95% of the action happens outside of 'within roll20'. If Chris initiates the action, his PC connects (quick) and sends it (quick). If someone else initiates the action, Chris'PC is waiting and not aware of the disconnect until after some timeout and retry.&nbsp; The displayed behaviour is exemplary of some one switch/router in the long path between Chris'PC and Roll20 servers dropping non-active connections aggressively. &nbsp;
