Asus firewall delays connections from outside?

[ColinTaylor]

- in synology's reverse proxy manager i have entered reverse proxy external port 443 and my main domain to internal port 443 and syno's local IP --> is that double forwarding and a loop caused? (honestly i don't know why is that...i guess old leftovers from testing...)

Thinking about it a bit more, I don't think this is necessary for your main domain name (e.g. mydomain.com). You'd typically use the reverse proxy for subdomains over the same port (e.g. mycameras.mydomain.com). But as I said, I'm no expert.

Yeah, it does work without that, so asus forward is only thing needed.
I figured it out "the mistery": synology has port 443 as port for proxy manager and 5001 (default, mine is different) for user interface. I've had this "main domain" entry forwarded to this UI port, so by entering "mydomain.com" i got to synology user interface. When we were discussing my problem i came to a point when i tried to change that port to 443 to see if it helps. A desperate act, i guess... i figured that out after i couldn't access syno's UI anymore...
