Hi, sorry for my bad english in advance, i hope you understand.
i made the port fowarding thing and i think i did good, but a few days ago my connection started to fail :
>>>Sometimes is like this:
Starting networking diagnostics...

Your local network port (UDP) is 16000. All game traffic is routed through this port. This can be changed in "Settings" -> "NAT Traversal".

Attempting to connect to 3 test servers. This will take around a minute to complete...

Received data from 'server 1' through port 16000 (this is your WAN or router port)
Received data from 'server 2' through port 16000 (this is your WAN or router port)
Received data from 'server 3' through port 16000 (this is your WAN or router port)

>>>But 5 minutes after is like this:

Test Result: Connection failure
Network Health: Failure
Recommended Action: Turn off firewall, disable firewall, or uninstall firewall, port forwarding, if none of that works reinstall your operation system or try to directly connect to the internet without a router. The only port you need to forward is UDP port 16000 on Voobly you do NOT need the direct play ports 2300-2400 and 47624.
Details: Connections to one or all of the servers failed

Anyway , even if pass all tests it cant connect (im almost always fp, that didnt happened before).Also the ''increasing scan'' never worked again (that worked fine before as well). It would be nice if yuou guys can help me with this, thanks in advance.
PD:i used the router detector and it informs me that i have 2 routers (i only have one in here)Im contacting my isp, but... it could be the reason for the failure?

Hi.

Can you please upload a screenshot of your port forwarding configuration in your router ?

Hi , i think this is what u asked me for

Delete 2300-2350

Also disable UPNP (in case it's already enabled on your router)

P.S: Double check your computers DHCP IP to see if it matches the one you are using in your port forwarding rule.

hi this are the screenshots, idk if u need some more

As informed on live chat, check with your ISP once and let us know what they have to say about it.

hi, i talked to my isp, it seems like i have 2 routers , one is my antenna (i think i should have sayed that before, sorry) now he fowarded the port to it and works, at least for now
Thanks anyway for the guidance
