Uhhhhhhh… what? No. Port forwarding is used to forward incoming traffic on port X to a device inside your network (still on port X). You don’t need any forwarding setup to talk to external IPs on port 80/443/whatever.
Even if you did - he posted on the forum which is using HTTPS - port 443.
Some firewalls do block outgoing traffic on uncommon ports, which would prevent access to cloud servers since the cloud servers generally use ports 10000-60000… but I highly doubt this is his issue. I’ve only seen one person with this problem on their local network in the whole time I’ve been playing… me.
Uhhhhh… no. Blockheads does not use Amazon AWS. I can’t recall what is used off the top of my head, but it’s not AWS. Will report back once I can check.
Don’t recommend this if there’s any other possible solution. Reinstalling will wipe all single player worlds, portal chest contents, and time crystals… and if it’s a network issue, won’t even help.
@OP I recommend following Shariu’s advice first. If that doesn’t work report back and we might be able to help more.
