Certification Error with public ip

Okay i tried to figure it out on my own but failed.

Tryin to put a Server online. I got a static IP, being behind a router, opend all the neccessary ports. The Server works over the local IP, but whenever i put in my Public ip the cert. fails.

As well tried Dr.Abd.. Tutorial , it didnt work out either.

Any idea ?

And i thought it's the "Ask the Experts" Section

You tried it with SrPatcher?

well i cant even get the certification workin with the public ip, so sr_patcher wont help.

Simple answer your router is analing you.
Therefore disable your firewall first please :3
Then go into ur Ini files match everything you need
then go into cert delete the save white thingy and then compile again then run it.
Should work fine. If not find an alternative broski
