Most people can use AhaSlides without doing anything special. AhaSlides will work fine as long as there are no restrictions from your internet service provider (ISP) or from your company, organisation or school, and you have a good and stable internet connection. If AhaSlides won’t load for you, the restriction is almost always coming from one of those two places.

​
Does AhaSlides work in China?

Many users in China can still use AhaSlides normally. For people who can’t, a VPN might work — but it isn’t stable, so we don’t recommend it. The same rule applies as anywhere else: as long as there are no restrictions from your ISP or from your company, organisation or school, and your internet is good and stable, AhaSlides will work fine.

​
How to whitelist AhaSlides

If AhaSlides is blocked at work or school, the restriction comes from your company, organisation or school network. Ask whoever manages that network to whitelist AhaSlides by passing on these steps:
1

Open the required ports

Open ports 443 and 80.
2

Whitelist the AhaSlides domains

Allow the following domains:
3

Allow WebSocket connections

Live sessions keep the presenter’s screen and participants’ devices in sync over secure WebSocket connections (wss://) on port 443 to presenter.ahaslides.com and audience.ahaslides.com. Make sure your firewall or proxy lets WebSocket traffic through to these domains, not only normal web pages. If WebSockets are blocked, slides and responses may not update live.

​
Restrictions from your internet provider

If the restriction is coming from your ISP rather than from your own network, whitelisting won’t help — you’ll need to contact your ISP about it directly.
