Forwarding port 443 causes internet problems to anyone else?

In the last couple of weeks, whenever I forward port tcp 443 I get internet issues.
All my other port forwardings work fine, except this one.

And it's disabled in IP SERVICES before someone asks :)
Seems to be on the latest versions, because today I messed around with an 6.43.16 RB and it worked fine.

Am I crazy? Or is this happening to someone else?

Https uses port 443... so by forwarding this port you create problems...!

Let me fix it:
Https uses port 443... so by incorrectly forwarding this port you can create problems...!
And whether it's the case, probably yes, but it's hard to tell exactly if you don't show your config.

My first guess is that your forwarding rule is not specific enough. For example, if you forward all port 443 traffic to something, then ALL traffic including your outbound https traffic will go there. On the other hand, it you only forward port 443 traffic that is inbound on your WAN connection, then your outbound http traffic will be unaffected.

What is the source you are trying to forward from and the destination?
