Connection problems

If you are having problems loading up the editor, or if you get a "PDF rendering error" message in the preview panel please check:

• Clear your browser's cookies and cache (especially the cookies)
• Use the Incognito/Private mode of your browser
• Disable any browser extensions/plugins especially ad-blockers and download managers, or firewalls/proxies, that you may be running
• Use a different browser or computer, or connect using a different network (home/network/mobile)
• Switch to a better DNS, e.g. Google's public DNS servers (https://developers.google.com/speed/public-dns/docs/using). This may help solve DNS resolution failures, which can prevent some scripts to load properly. The default DNS are usually set by your internet service provider or private network, and might sometimes be out of date and cause transitional issues.

To help narrow the issue please see if:

• Do other projects work?
• Do other browsers work?
• Can you load up with other internet connections?
