Browser and network issues

Most Dubly.AI issues that look like product bugs are actually browser or network problems. Work through this list before opening a ticket.

Supported browsers

Browser	Minimum version
Chrome	110+
Edge	110+
Firefox	115+
Safari	16.4+

Anything older works partially but is unsupported. Use Chrome for best experience.

Common browser issues

App won't load

Hard refresh: Cmd/Ctrl + Shift + R
Try an incognito / private window
Disable privacy extensions that block analytics or session cookies

Features greyed out

Missing permissions — make sure third-party cookies are enabled for *.dubly.ai
Browser too old — update

Uploads fail or stall

Disable download managers or browser extensions that interfere with XHR uploads
Pause competing downloads
Try a different browser

Editor is slow or freezes

Close other tabs (video editing is memory-heavy)
Reduce browser zoom to 100%

Network and connectivity

Required connectivity

Minimum upload speed: 10 Mbps for source uploads
Minimum download speed: 25 Mbps for preview playback of 4K exports

Corporate firewall checklist

Allowlist:

app.dubly.ai
upload.dubly.ai
cdn.dubly.ai
api.dubly.ai
websocket.dubly.ai (or WebSocket over port 443)

Ask your IT team to whitelist these before rolling out to the team.

VPN issues

Some corporate VPNs break WebSocket connections → editor won't update live
Try disconnecting the VPN and using the corporate allowlist instead

DNS

If app.dubly.ai doesn't resolve, try 8.8.8.8 or 1.1.1.1 DNS temporarily
Clear DNS cache: ipconfig /flushdns (Windows) or sudo killall -HUP mDNSResponder (macOS)

Mobile browsers

Review, share, and playback work on mobile.
Editing is supported but the experience is best on desktop.
Some uploads limited by iOS/Android memory — use desktop for files > 500 MB.
