Extensions and Plug-Ins
Some browser extensions and plug-ins are known to interfere with
the way Coggle works. To test if this is causing your problem try
running Coggle in a private window (if your browser supports this
feature), or by temporarily disabling your browser extensions.
Try a Different Browser
If your browser is supported but Coggle still isn't working, we
recommend temporarily trying a different browser. As hard as we try
to prevent them, browser specific problems can sometimes slip
through our testing. If you think you've found a bug then drop us
an email and we can make
Coggle a little better for everyone!
Coggle uses a technology called WebSockets to make sure the changes you make to your Coggles reach us as fast as possible. Some anti-virus software is known to interact badly with WebSockets. You can try temporarily disabling this software, or exclude Coggle from its checks.
If your software allows you to exclude domains from its checks, add the following domains: *.coggle.it, ws.coggle.it, and coggle.it.
This is a useful tool for checking whether your browser is able to setup WebSocket connections: websocketstest.com. Your browser must pass at least the WebSockets (Port 443, SSL) test to work with Coggle.
Failing WebSockets
Software or firewall settings may be interfering with your connection to Coggle.
Low bandwidth
If your bandwidth results are in kbps (rather than Mbps), the problem may be due to a slow internet connection.
CDN Errors
There may be a problem connecting to Amazon CloudFront. Coggle
uses a CDN to let files that don't change very often reach your
computer in the fastest time. The domain we use for our CDN is
static.coggle.it.
Proxy or firewall settings
Proxies and firewalls can sometimes interfere with Coggle connections. Whitelisting *.coggle.it often resolves the problem.
