One of my player couldn't go past the loading page

Hello, On Thursday night (21h00 GMT+1 time), one of my players has encountered a problem entering my campaign. He couldn't go past the loading page. He cleaning his chrome cache. Disabled his firewall/antivirus. Rebooted his PC. Nothing would work. He has the same ISP as me and several other players in the campaign. He finally could join us by using firefox (after encountering the same problem for several minutes) instead of chrome (he is not using chrome for something else than Roll20, has no plugin for chrome and has the latest version). It took him nearly 15 minutes to connect. On Wednesday, the same player connected to the same campaign without problem with chrome. We were playing on the dev server for the first time, but this player has encountered the problem on the production server on several occasions (which were resolved by hitting reload, clearing the cache and sometimes just trying to reconnect without doing anything special. I had the same problem on several occasions on several computers which were working just hours/minutes ago (without firebase or roll20 server problem signalled on this day). Repeatedly Hitting reload, correct the problem for me. On a side note, on Thursday night, another player was regularly (more than 10 times) disconnected and reconnected. Luckily He hadn't any problem to reconnect.

I'm sorry you're having trouble with the site. Can you please have the player follow Steps 1-3 of our Solving Technical Issues wiki page, taking special care to temporarily disable all browser add-ons and extensions, temporarily pause your anti-virus, and try switching browsers (for Chrome/Firefox specific issues) to see if one of those components is causing the problem. If all of that fails, please follow Step 4 , including providing all of the necessary information, so that we can further assist you. If it is possible, having them post here might be the most useful.

My players (and myself) did follow the step 1-3, stopped firewall/antivirus changed browsers... but the issue still appears from time to time. It seems random and appears with windows7 and MacOS and a very different PCs configurations. It seems to solve itself each time randomly (after a few minutes) and i opened this thread to signal this recurring problem, hoping that that it'll alert the roll20 team that it seems that something is wrong with the Roll20 loading process or with my current campaign.

Laurent, next time it happens can you capture the console log so that we can see what specifically is failing?

No problem, we'll do that the next time it happens.

Laurent, Firebase which is what is being blocked are our servers. That means some third party process isn't allowing him to connect. Either an extension, antivirus, or firewall. Recently I saw this same issue with a DNS blocking loading in javascript files. <a href="https://wiki.roll20.net/Solving_Technical_Issues" rel="nofollow">https://wiki.roll20.net/Solving_Technical_Issues</a>

Hi, The problem i see with 'some third party process isn't allowing him to connect" is that i logged into roll20 with the same PC, same session, no reboot no change of firewall, ... 2 hours before that. A few minutes later, i was connected without problem. (without changing anything, just took the time to write this technical issue) It seems to be the same problem my player had. It works, then it doesn't work. Then it works. Can't it be a connectivity problem with firebase ? Servers refusing connection because of heavy traffic ? or some other server connection intermitant bug ?

Check out the DNS issue I linked in my previous post.

Thank you, we'll try to flush the DNS cache the next time this problem arise.
