Getting connection to server has been interrupted error

I get this intermittent error as GM: I tried the laundry list of fixes: cleared cache, turned off extensions in Chrome, I have the updated version. It tends to run fine for a while, then I get the error again. Here is the details from the my console log, per the 'solving technical problems' faq: Any ideas what is going wrong? Consider using 'dppx' units instead of 'dpi', as in CSS 'dpi' means dots-per-CSS-inch, not dots-per-physical-inch, so does not correspond to the actual 'dpi' of a screen.

Riley, It happens about every 5 minutes or so. The last time I logged in, the warning appeared after a minute, stayed on for about five minutes, then came back after about four minutes and then on for another five minutes... and so on. It seems to occur more often when I switch maps. Could this be from loading of tabletop elements? I am using wifi at home. I switched to ether wire connected to the router: still happened. My ISP is reliable, but not fast (~1mbps). The maps take a while to load and the virtual dice crawl out onto the tabletop; I can hear my players cheer or sneer over VOI long before the dice finally stops rolling. Other than one time where I could not see the map, there has not appeared to be any trouble loading in tiles and tokens. UPDATE Logged on w/ player. Could not connect via voice or video. Continued to get error and maps were slow to load or did not load at all. We switched to the non-dev server and then got voice and video some of the time. Got the error box once, then the page continued to reload every few minutes.

Okay, I tried various fixes including the ...forcelongpolling=true. Still get the error. I also get it on my laptop on the same ISP (both computers are macs). I switched to firefox (virgin load, no addons) and still get the error. I also turned off iMac's firewall. Still there. It must be my awful, awful Internet provider. It's a shame because this all worked beautifully the first two games we played.

I've been working with my Internet provider -- they replaced my router and switched me to a less busy DSLAM circuit. The connection is now faster than it was. So far, I have not gotten the error since the switch. I am going to test tonight with some players to make sure. Fingers crossed!
